Two boats pull a 75.0 kg water skier with a 45° from the skier to each boat (90° between altogether). (a) If each boat pulls with a force of 600 N and the skier travels at a constant velocity, what is the magnitude of the resistance force from the water on the skier? (b) Assuming the resistance force remains constant, if the boats now pull with a force of 700 N each what is the magnitude of the acceleration of the skier?

we need to know the time interval during which the force acts. impulse of force = momentum change

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
