QUESTION 3 As a baseball is being caught, its speed goes from 20.D to D mis in about 0.00750 s. Its mass is 0.185 kg. (b) What is the magnitude of the force acting on it? QUESTION 4 Three sled-dogs pull on a sied on snow. The sled is initially moving at a speed of 12.5 m/s when the dogs start pulling harder for about 1.25 s, causing the sled to move with a final speed 18.0 mis. If the sled has a total mass of 458 kq, what is the force exerted by the dogs on the sled in this time interval? QUESTION S At the end of an amusement park ride, it is desirable to bring a gondola to a stop without having the acceleration exceed 2g (This means twice the acceleration of gravity). If the total mass of the gondola and its occupants is 2,000 kg, what is the maximum allowed force
