Chapter 1: Programming Project 5:

(Physics: acceleration)

Average acceleration is defined as the change of velocity divided by the time taken to make the

change, as shown in the following formula:

a = (v1 - v0) / t Here, v0 is the starting velocity in meters/second, v1 is the ending velocity in meters/second, and t is the time span in seconds.Assume v0 is 5.6, v1 is 10.5, and t is 0.5, and write the code to display the average acceleration.

# Exercise01_02Extra print((10.5 - 5.6) / 0.5)

Quiz 2.5 #1:

Assign 7 to a variable named seven.

seven = 7

Quiz 2.5 #2:

Define a variable precise and make it refer to 1.09388641.

precise = 1.09388641

Quiz 2.5 #3:

Define two variables, one named length making it refer to 3.5 and the other named width making it refer to 1.55.

length = 3.5 width = 1.55

Quiz 2.6 #1:

Variables i and j each have associated values. Swap them, so that i becomes associated with j's original value, and j becomes associated with is original value. You can use two more variables itemp and jtemp.

Note: This question does not follow our naming convention for

variables. itemp and jtemp should have been named iTemp and jTemp.

itemp = i jtemp = j i = jtemp j = itemp

Quiz 2.6 #2:

Given two already defined variables, i and j, write a statement that swaps their associated values.

i, j = j, i

Quiz 2.6 #3:

Given two variables matric_age and grad_age, write a statement that makes the associated value of grad_age 4 more than that of matric_age.

Note: This question does not follow our naming convention for

variables. matric_age and grad_age should have been named matricAge and gradAge.

grad_age = matric_age + 4

Quiz 2.8 #1:

Given the variables taxable_purchases and tax_free_purchases (which already have been defined), write an expression corresponding to the total amount purchased.

Note: This question does not follow our naming convention for

variables. taxable_purchage and tax_free_purchase should have been named taxablePurchage and taxFreePurchase.

taxable_purchases + tax_free_purchases

Quiz 2.8 #2:

Given the variables full_admission_price and discount_amount (already defined), write an expression corresponding to the price of a discount admission.

full_admission_price - discount_amount

Quiz 2.8 #3:

Given the variable price_per_case, write an expression corresponding to the price of a dozen cases. 3 / 4

Note: This question does not follow our naming convention for

variables. price_per_case should have been named pricePerCase.

price_per_case * 12

Quiz 2.8 #4:

Given the variables cost_of_bus_rental and max_bus_riders, write an expression corresponding to the cost per rider (assuming the bus is full).

cost_of_bus_rental / max_bus_riders

Quiz 2.8 #5:

Write an expression that computes the remainder of the variable principal when divided by the variable divisor. (Assume that each is associated with an int.)

principal % divisor

Quiz 2.8 #6:

Write an expression that computes the average of the values 12 and 40, and assign it to the variable avg, which has already been defined.

avg = (12 + 40) / 2

Quiz 2.8 #7:

You are given two variables, both already defined. One is named price and is associated with a float and is the price of an order. The other is total_number and is associated with an int and is the number of orders. Write an expression that calculates the total price for all orders.

price * total_number

Quiz 2.8 #8:

You are given two variables, both already defined, one associated with a float and named total_weight, containing the weight of a shipment, the other associated with an int and named quantity, containing the number of items in the shipment. Write an expression that calculates the weight of one item.

total_weight / quantity

Quiz 2.8 #9:

Assume there is a variable, h already assigned a positive integer value. Write the code necessary to assign its square to the variable g. For example, if h had the value 8 then g would get the value 64.

g = h * h

Quiz 2.8 #10:

Assume that price is an integer variable whose value is the price (in US currency) in cents of an item. Assuming the item is paid for with a minimum amount of change and just single dollars, write an expression for the amount of change (in cents) that would have to be paid.
