A 0.15 kg baseball is moving at 35 m/s toward home plate when it is hit with the bat. The ball is in contact with the bat for 0.0019 s, and leaves the bat at 25 m/s directly away from home plate. Determine the average force exerted by the bat on the ball.

7. During a snowball fight, a 0.30-kilogram snowball traveling at a speed of 17.0 m/s hits a student in the back of the head. If the contact time is 0.10 s, what is the magnitude of the average force on the student's head? N ssf f60° Ossi 09 JS 50 ssf60

A 142g baseball is moving at 17.0 m / s in the + x direction. When hit with a bat by a baseball player, its final velocity is 21.0 m / s in the -x direction. The bat acts on the ball for 6.0 x 10⁻² s. What is the magnitude of the average force exerted by the bat on the ball?

A golf club strikes a golf ball. The club and the ball remain in contact for 0.6ms. The 35gram ball leaves the club with a speed of 60m/s. Calculate the average force of the club to the ball.

A 4.10-kg steel ball strikes a wall with a speed of 11.0 m/s at an angle of ? = 60.0° with the surface. It bounces off with the same speed and angle (see figure below). If the ball is in contact with the wall for 0.200 s, what is the average force exerted by the wall on the ball? (Assume right and up are the positive directions.) Fx =   Fy =

A baseball (m= 150 g) approaches a bat horizontally at a speed of 43.9 m/s (98.2 mi/h) and is hit straight back at a speed of 52.6 m/s (118 mi/h). If the ball is in contact with the bat for a time of 1.27 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction. Number i Units VO Vf

A baseball with a mass of 148 g is thrown horizontally with a speed of 39.1 m/s (87 mi/h) at a bat. The ball is in contact with the bat for 1.00 ms and then travels straight back at a speed of 45.3 m/s (101 mi/h). Determine the average force exerted on the ball by the bat. Neglect the weight of the ball (it is much smaller than the force of the bat) and choose the direction of the incoming ball to be positive. (Indicate the direction with the sign of your answer.)

A 375 gram basketball is bounced off of a wooden board, as shown below. It is moving straight down at a speed of 4.75 m/s just before hitting the board, and it is moving with a speed of 3.75 m/s at an angle of 27.5 degrees above the horizontal just after. The ball is in contact with the board for a total of 68.5 milliseconds (ms). A)Find the average force that the board exerts on the ball during the bounce. Give the magnitude of the force in units of Newtons. Give the direction of the force as an angle from the x-axis, in degrees.  B) How much kinetic energy is lost as a result of the ball hitting the board? Give your answer in Joule

A baseball (m = 148 g) approaches a bat horizontally at a speed of 40.7 m/s (91.1 mi/h) and is hit straight back at a speed of 51.6 m/s (115 mi/h). If the ball is in contact with the bat for a time of 1.45 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction.
