- If a 0.50-kg block initially at rest on a frictionless, horizontal surface is acted upon by a force of 6.8 N for a distance of 5.4 m, then what would be the block's velocity?A 945-kg car starts from rest on a horizontal roadway and accelerates eastward for 5.00 s when it reaches a speed of 30.0 m/s. What is the average force exerted on the car during this time? ( in kN eastward)A car of mass 931 kg coasts on a level road, starting with an initial speed of 15.7 m/s and coming to rest 14.7 s later. Find the frictional force acting on the car.
- As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 22.0 m/s. In the process, he moves his hand through a distance of 1.20 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed.As a fish jumps vertically out of the water, assume thatonly two significant forces act on it: an upward force F exertedby the tail fin and the downward force due to gravity. A recordChinook salmon has a length of 1.50 m and a mass of 61.0 kg.If this fish is moving upward at 3.00 m/s as its head first breaksthe surface and has an upward speed of 6.00 m/s after twothirdsof its length has left the surface, assume constant accelerationand determine (a) the salmon’s acceleration and (b)the magnitude of the force F during this interval.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.

- When serving a tennis ball, the player hits it when its velocity is zero (at the highest point of a vertical toss). The racket exerts a force of 510 N on the ball for 5.00 ms, giving it a final velocity of 47.0 m/s. Using these data, find the mass (in g) of the ball.As a protest against the umpire’s calls, a baseball pitcherthrows a ball straight up into the air at a speed of 20.0 m/s. Inthe process, he moves his hand through a distance of 1.50 m.If the ball has a mass of 0.150 kg, find the force he exerts onthe ball to give it this upward speed.Problem 5: Rafael drops a hard rubber ball, of mass m = 310 g, onto the pavement. He drops it from a height h = 2.9 m, and it bounces back to a height h = 1.65 m. While the ball is in contact with the ground, the ground exerts a non-constant force on the ball as shown in the figure. During the time interval At¡ the force rises linearly to Fmax, and during the time interval At, the force returns linearly to zero as the ball leaves the ground. Refer to the figure. F Fmax Ati At2
