1.) a baseball player catches a 0.138kg baseball moving at 32 m/s
a.) what is the average force needed to stop the baseball by a mitt held in a stationary position if it takes 0.04s to stop the ball
b.) the baseball player decides to try catching the ball by letting the mitt move backwards during the catch so that it takes 0.40s to stop the ball. What is the average force under this condition.
2.) A police officer fires his gun into a ballistics test container. he fires a 5.0g bullet into the container and it stops in 0.025s. The bullet velocity is 335 m/s just as it reaches the sand in the container. What is the average force exerted on the bullet to stop it.

Baseball. A catcher catches a 145 g fastball traveling horizontally at 42.5 m/s. How large an impulse does the ball give to catcher? If the ball takes 20.0 ms to stop once it is in contact with the catcher’s mitt, what average force did the ball exert on the catcher? What is the baseball's average acceleration during this interval? (answer is in meters per square second, you only need to type the number not the units on this one)
A pitcher throws a 0.145 kg baseball at 40.19 m/s at the catcher (who is standing still). It takes the catcher 0.07 seconds to stop the baseball after catching it. What was average force required to catch the ball?
8.34 A catcher catches a 145 g baseball traveling horizontally at 30.0 m/s . A. How large an impulse does the ball give to the catcher? ANSWER: p= ___________ Kg*m/s B. If it takes the ball 25.0 ms to stop once it is in contact with the catcher's glove, what average force did the ball exert on the catcher? ANSWER: F= __________ N
(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...
