Changing which factor would NOT have an influence on the kinetic energy of a moving van loaded with 100 kg bags mulch of with a total mass of 1,500 kg. The vehicle is traveling across an open parking lot at a speed of 5 m/s. Question 8 options:

A: direction the moving van is going across the parking lot.

B: increasing the rate of speed without altering the mass of the vehicle or its contents.

C: emptying the moving van one bag at a time at a constant rate.

D: adding more contents (increasing the overall mass) to the van while the van is in motion traveling 5 m

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.

In the sport of parasailing, a person is attached to a rope being pulled by a boat while hanging from a parachute-like sail. a rider is towed at a constant speed by a rope that is at an angle of 15 ∘ from horizontal. the tension in the rope is 1900 n. the force of the sail on the rider is 30∘ from horizontal. what is the weight of the rider? express your answer with the appropriate units.
