Two forces F1and F2 produce the same impulse on two different objects. The magnitude of the average force of  F1 is eight times that of F2.If the average force F1 acts for a time interval of 1.1 ms, determine the time interval (in ms) the average force F2 acts

An insurance company is testing air bag safety. Car A has front air bags and Car B does not. In both cases, the cars are driven into a brick wall with the same momentum. In Car A, the dummy survives, but in Car B, the dummy does not. In terms of impulse and force, please explain this result. The dummy in Car B experienced a greater impulse and a greater force than in Car A. O The dummy in Car B experienceda greater impulse but the same force as in Car A. The dummy in Car B experienced the same impulse but a greater force than in Car A. O The dummy in Car B experienced the same impulse and the same force as in Car A. O Not enough information to determine.

A model rocket is constructed with a motor that can provide a total impulse of 26.0 N-s. The mass of the rocket is 0.117 kg. What is the speed that this rocket achieves when it is launched from rest? Neglect the effects of gravity and air resistance. Number i Units

A 0.269 -kg volleyball approaches a player horizontally with a speed of 12.6 m/s. the player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 22.5 m/s.  A. what impulse is delivered to the player ? ( take the direction of the final velocity to be the positive direction. indicate the direction with the sign of the answer.) B. if the player's fist is in contact with the ball for 0.0600s find the magnitude force exerted on the player's fist.
