Here are the velocities (at that instant) and the forces: (1) =(-41) m/s, F= (61-201) N; (2) = (2-3)) m/s, F=(-2) + 7k) N; (3) v = (-3i+j) m/s, F= (21+ 6j) N.

Hi I am in physics I, and they have the problem: In a baseball game, the 145g ball reaches the batter with a speed of 15.0m/s. The batter hits the ball with a force as shown in exact oppositie direction. The peak force (F max) is 1500N. Find the ball speed right after the hit. It was solved like: J= mvf - mvi area=1/2*b8h J= area = 1500(6)/2 + 1500(2)/2 J=6000 J=6.0 N*s 6.0 N*s = (0.1 +5kg)vf - (0.145kg)(-15) solve for vf vf=26.38 I really don't understand where 0.1 came from. If you can just break down i bit how this is solve that would be great. Thanks!
A soccer ball with mass 0.460 kgkg is initially moving with speed 2.10 m/sm/s. A soccer player kicks the ball, exerting a constant force of magnitude 38.0 NN in the same direction as the ball's motion. Over what distance must the player's foot be in contact with the ball to increase the ball's speed to 6.00 m/sm/s? Express your answer in meters
A golf club strikes a 0.062-kg golf ball in order to launch it from the tee. For simplicity, assume that the average net force applied to the ball acts parallel to the ball’s motion, has a magnitude of 6120 N, and is in contact with the ball for a distance of 0.0080 m. With what speed does the ball leave the club?
A freight train consists of two 9.00 ✕ 105 kg engines and 50 cars with average masses of 3.50 ✕ 105 kg. (a) What force (in N) must each engine exert backward on the track to accelerate the train at a rate of 4.00 ✕ 10−2 m/s2 if the force of friction is 7.50 ✕ 105 N, assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains is small, and consequently, trains are very energy-efficient transportation systems. (Enter the magnitude.) b) What is the magnitude of the force (in N) in the coupling between the 37th and 38th cars (this is the force each exerts on the other), assuming all cars have the same mass and that friction is evenly distributed among all of the cars and engines? (Assume both engines are at the front of the train.)
