If a 0.50-kg block initially at rest on a frictionless, horizontal surface is acted upon by a force of 2.7 N for a distance of 3.9 m, then what would be the block's velocity?

how long does it take a 2500 kg car to slow down from 15 m/s if it strikes a wall with a force of 10,000 N assuming that the wall is elastic?

The last segment of the triple jump track-and-field event is the jump, in which the athlete makes a final leap, landing in a sand-filled pit. Assuming that the velocity of a 80-kg athlete just before landing is 9 m/s at an angle of 35° with the horizontal and that the athlete comes to a complete stop in 0.22 s after landing, determine the horizontal component of the average impulsive force exerted on his feet during landing.

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 0.7 ball falls down and hits the floor at a speed of 15 m/s. The ball then bounces back up at aspeed of 12 m/s. If the ball was in contact with the floor for 0.06 s, what was the average force from the floor on the ball?

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 0.50-kg block slides across a table top with an initial speed of 20 cm/s and comes to rest on a distance of 70 cm. Find the average friction force that retarded its motion.

After falling from rest from a height of 28 m, a 0.35-kg ball rebounds upward, reaching a height of 18 m. If the contact between ball and ground lasted 2.5 ms, what average force was exerted on the ball? ( enter the magnitude)

After falling from rest from a height of 31 m, a 0.60-kg ball rebounds upward, reaching a height of 21 m. If the contact between ball and ground lasted 2.5 ms, what average force was exerted on the ball?

During a practice dive, a 45-kgkg diver jumped to a maximum height of 4.4 mm above the water before coming down and entering the water. She came to rest 0.40 ss after hitting the water. Determine the average force that the water exerted on her while stopping her.
