Question 1

1.

Choose the most appropriate version of the impulse equation given the following scenario:

What is the impulse generated when a 23 kg cart is pushed with a force of 60 N to make it go from rest to 8 m/s?

J = Ft

J = m∆v

J = m∆v = Ft

m∆v = Ft

Question 2

2.

What is the impulse generated when a 23 kg cart is pushed with a force of 60 N to make it go from rest to 8 m/s? Show all work using GUESS method and be sure to include units on your final answer.

Question 3

3.

Choose the most appropriate version of the impulse equation given the following scenario:

A 4 kg water balloon flies through the air at 8 m/s. If it lands on a cushion that takes 1.2 seconds to bring it to a stop, how much force is exerted on the balloon during the landing?

J = Ft

J = m∆v

J = m∆v = Ft

m∆v = Ft

Question 4

4.

A 4 kg water balloon flies through the air at 8 m/s. If it lands on a cushion that takes 1.2 seconds to bring it to a stop, how much force is exerted on the balloon during the landing? Show all work using GUESS method and be sure to include units on your final answer.

Question 5

5.

Choose the most appropriate version of the impulse equation given the following scenario:

What is the impulse generated when a 93 kg mule is pushed with a force of 120 N for 1.8 seconds?

J = Ft

J = m∆v

J = m∆v = Ft

m∆v = Ft

Question 6

6.

What is the impulse generated when a 93 kg mule is pushed with a force of 120 N for 1.8 seconds? Show all work using GUESS method and be sure to include units on your final answer.

Question 7

7.

Choose the most appropriate version of the impulse equation given the following scenario:

A 75 kg person is brought to a stop by their seatbelt. If the seatbelt applies 700 N of force over a period of 0.8 seconds, what was the original velocity of the person (and the car they were riding in)?

J = Ft

J = m∆v

J = m∆v = Ft

m∆v = Ft

Question 8

8.

A 75 kg person is brought to a stop by their seatbelt. If the seatbelt applies 700 N of force over a period of 0.8 seconds, what was the initial velocity of the person (and the car they were riding in)? Show all work using GUESS method and be sure to include units on your final answer.

Question 9

9.

A motorcycle being driven on a dirt path hits a rock. Its 80 kg cyclist is projected over the handlebars at 30 m/s into a haystack. The cyclist is brought to rest in 0.6 seconds. What is the magnitude of the average force exerted on the cyclist by the haystack? Show all work using GUESS method and be sure to include units on your final answer.
