A baseball catcher is performing a stunt for a television commercial. He will catch a baseball (mass 145 g) dropped from a height of 60.0 m above his glove. His glove stops the ball in 0.0100 s. What is the force exerted by his glove on the ball?

After visiting a delicatessen in the local mall, a student takes the elevator down to the parking garage and uses a spring scale to "weigh" his pastrami sandwich. At a certain instant of time, the elevator, student and sandwich are moving down at a speed of 2.00 m s² 1.00 m/s, and speeding up at a rate of At this instant of time, the spring scale reading is 5.60 N. 24. The weight of the pastrami sandwich is equal to C. 4.65 N. A. 5.60 N. В. 6.74 N. D. 7.04 N. E. 6.24 N. 25. The resultant force acting on the sandwich is equal to A. 1.27 N up. B. 1.44 N down. C. 1.27 N down. D. 1.38 N up. E. 0.949 N up.

Two blocks are suspended from opposite ends of a light rope that passes over a light, frictionless pulley. One block has mass m1 and the other has mass m2, where m2 > m1. The two blocks are released from rest, and the block with mass m2 moves downward 5.00 m in 2.00 s after being released. While the blocks are moving, the tension in the rope is 16.0 N. Calculate m1 and m2.

A ball of mass m = 1.55 kg is released from a height of h = 2.8 m into a tank of water. At a time of t = 1.08 s after hitting the surface of the water, the ball's velocity has decreased by 50%. 1) What is the magnitude of the average force the ball experiences, in newtons, during the time t?

Two boxes are at rest on a smooth, horizontal surface. The boxes are in contact with one another. If box 1 is pushed with a force of magnitude F = 12.6 N, the contact force between the boxes is 9.00 N; if, instead, box 2 is pushed with the force F, the contact force is 3.60 N. In either case, the boxes move Part A together with an acceleration of 1.80 m/s What is the mass of box 1? kg Submit Request Answer Part B What is the mass of box 2?

Blocks with masses of 1.0 kg, 2.0 kg, and 3.0 kg are lined up in a row on a frictionless table. All three are pushed forward by a 12 N force applied to the 1.0 kg block. How much force does the 2.0 kg block exert on (a) the 3.0 kg block and (b) the 1.0 kg block?

A 0.55 kg football is thrown with a velocity of 17 m/s to the right. A stationary receiver catches the ball and brings it to rest in 0.021 s. What is the force exerted on the receiver?Answer in units of N.

A flea jumps by exerting a force of Flea = -1.52 x 10-5 ĵ N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of = ( 10-5 î + 2.44 × 10¬5 k) N on the flea. Find the acceleration of the flea if its mass is 6.00 x 10-/ kg. Express your answer in vector form. Assume that the +x axis is to the Fwind -4.64 right, the +y axis is up along the page, and the +z axis is out of the screen towards you as shown in the figure below. -77.33i – 25.33j + 40.66k a =

A net force is applied in the positive directions to an object moving in one dimension. The graph of the force is below. The mass the object is 2.00kg . If the initial velocity of the object is m -1.00- what is the velocity of the object after this force is applied? S 4 1 2 3 4 time (s) force (N)

A student takes the elevator up to the fourth floor to see her favorite physics instructor. She stands on the floor of the elevator, which is horizontal. Both the student and the elevator are solid objects, and they both accelerate upward at 5.35 m/s2. This acceleration only occurs briefly at the beginning of the ride up. Her mass is 88.0 kg. What is the normal force exerted by the floor of the elevator on the student during her brief acceleration? (Assume the direction is upward.)
