Using the equation f=mv/t and the example problem given in the leture answer the following problem. A kick-ball of mass 0.5 kilograms is moving at 4 meters/second after being kicked. The kick lasted 2 seconds. How much force was used to kick the ball?_____newton.

Let a mass of 3.0 kg be standing still and a secondmass of 5.0 kg come along and hit it with velocity 4.0 m/s. Supposethe smaller mass moves off with a speed of 5.0 m/s.a) Draw a diagram to describe the situation before the collision.b) What is the velocity of the 5.0 Kg mass after the collision?c) Draw a diagram to describe the situation after the collision.d) What type of collision is it? Support your answer with calculations from Lawof Conservation of Momentum, and Law of Conservation of Energy.

A 1000kg "Smart Car' is stopped at an intersection. A large 4000kg SUV approaches from behind with a velocity of 15m/s and finds itself on a sheet of ice, unable to slow down or change direction. The cars collide in a perfectly inelastic collision which lasts 0.1 seconds. a. Calculate the average force and acceleration that each car experiences during the collision. b. Calculate the average net force that would be exerted on a driver of mass 50 kg if he/she was in either car. Compare these forces to weight, e.g., twice as large as gravity.

In a game of dodgeball, an opponent throws a 0.3 kg ball going 15 m/s at you and hits you in the chest. If your body exerts a force of 30 N for 0.25 seconds on the ball, how fast does it bounce off? 1. identify the system  2. draw a quick sketch of the initial state of the object(s) 3. do a momentum bar chart

complete the following 3 steps. 1. Indicate what your chosen system is (which objects are included in the system?) as well as your initial and final instants. Explain how your choice will help you solve the problem. 2. Draw a momentum-impulse bar chart for your chosen system that is consistent with the information given. 3. Write an equation using the bar chart as a guide and solve for any unknowns. A 6-kg bowling ball moving at 3 m/s hits a single 2-kg pin, knocking it forward at 6 m/s. If the collision took 0.050 s, what average force was exerted on the pin?

1. Suppose a clay model of a koala bear has a mass of 0.25 kg and slides on ice at a speed of 0.85 m/s. It runs into another clay model, which is initially motionless and has a mass of 0.45 kg. Both being soft clay, they naturally stick together. Friction on ice can be neglected. A sketch depicting the collision in Part 1 should have looked like this. V₁ Before collision O % 5 I T G O Koala bear clay model O Second clay model O both the clay models (a) To find the combined final velocity of the clay models, how will you define a system? 16 40 H After Collision 17 4- & (b) In the system in part (a), the forces of collision between the clay models are: 7 hp U * m₁ 00 8 m₁ m₂ T 9 m₂ v₂ 0 J K V1,2 V f O ? 11 I - P 52°F { + Co 940) O [ = insert } 11:39 AM 10/28/2022 1 prt sc 4 backspa 1 pause
