A paintball gun shoots a small hollow sphere filled with paint, which usually bursts on impact to splash paint on whoever is hits. Consider the two scenarios: (a) a paintball hits you and bursts and (b) a paintball hits you and bounces off. Assuming both paintballs have the same mass and velocity, which will hurt you more? (Which exerts the most force?) Both will hurt exactly the same amount. It is impossible to know without knowing the forces. The paintball that bounces off you. The paintball that burst.

Imagine that you are in a room and there is a door you want to close. The building is a little biton fire, and there is a fire on the hallway, so you want to close the door to keep the fire on thehallway from coming in the room, but you don’t want to get close.Finding two balls of same mass in the room. One of the balls will stick to the door the other onewill bounce.Which one do you want to throw to the door to impact the max P to the door?

A knight atop a high castle is preparing a canon to fire. The canon is aimed horizontally, and just as the canon fires, the knight clumsily knocks over a spare canonball off the wall and it falls vertically down to the ground. Assuming both canonballs leave the wall from the same height, which will hit the ground first? Both hit the ground at the same time. The canonball that falls vertically down. The canonball fired from the canon.

Ignoring air resistance, after being dropped the vertical velocity of a ball immediately before contacting a surface is dependent on: Question 18Answera.the height from which the ball was dropped and gravityb.the height from which the ball was dropped, gravity and the surface texture of the ballc.the height from which the ball was dropped, gravity, the mass of the ball, and surface texture of the balld.the height from which the ball was dropped, the mass of the ball, and surface texture of the balle.the influence of gravity, the mass of the ball and surface texture of the ball

If you kick a ball, you apply an impulse. The impulse is equal toGroup of answer choicesThe momentum of the ball.The momentum of your foot.The maximum force between your foot and the ball.The change in momentum of the ball.

A small ball of mass 1 kg moving with a velocity of 12 m/s undergoes a direct central impact with a stationary ball of mass 2 kg. The impact is perfectly elastic. The speed (in m/s) of 2 kg mass ball after the impact will be::
