ANSWER QUESTIONS 1-3 PLEASE!!!

1. A snowball that is 178 grams fall to the ground. It hits the floor with a speed of 5.42 m/s, bounces, and leaves the floor (going vertically up) with a speed of 3.16 m/s. Determine the magnitude of the impulse given to the ball while it was in contact with the ground.

2. A vehicle has a mass of 1,240 kg and a velocity of 22.4 m/s northward, and another vehicle has a mass of 1,410 kg, and a velocity of 18.7 m/s eastward approach an intersection, arrive simultaneously, and undergo a completely inelastic collision, tangling together. Determine the speed of the cars right after the collision?

3. A wheel starts spinning with an angular velocity of 18.4 rad/s. It begins to go through a uniform angular acceleration slowing to 12.2 rad/s during the next 5.80 seconds. Determine how many revolutions does the wheel turn during this time.
