- A cart of mass 0.85 kg is on a track, connected by a string over a pulley to a hanging mass of 0.1 kg. A friction pad is attached to the bottom of the cart, and you push the cart so that it first moves toward the sensor, then away from the motion sensor. The net acceleration of the cart does which of the following? a. always points away feom the motion sensor b. always points toward the motion sensor c. the direction of the net acceleration cannot be determined7. Using two ropes, Eric and Arya pull Josh on a skateboard. There is an angle of 35° between Eric and Arya. Eric pulls with a force of 300N and the resultant force is 500N. Determine the angle the resultant force makes with Eric's force. Include a detailed diagram. a. b.

A child sits on a sled at the top of a hill, the hill makes an angle of 20° with the horizontal. The child's mass is 40kg. Use us = .1 and 4.03 a. b. Draw a free body diagram for this system. Does the child accelerate down the hill? *i.e., check that the coefficient of static friction is vercome by the component of the childs weight in the direction the child would accelerate. If they do, what is their acceleration? *use coefficient of kinetic friction in sum of the forces balance if the child moves.
