The cart is initially at rest but is then pulled up the ramp with a force sensor attached to James. The force sensor exerts a force on the cart parallel to the ramp. Negligible friction acts on the cart. What force is required for James to pull the cart up the ramp at an acceleration of 2.5 m/s2?Three blocks are suspended at rest by the system of strings and frictionless pulleys shown in the figure below, where W = 48.0 N, and 0 = 32.1°.

- Only two horizontal forces act on a 6.8 kg body. One force is 7.9 N, acting due east, and the other is 6.6 N, acting 40° north of west. What is the magnitude of the body's acceleration? Number i Units6. Two blocks, with masses shown are pulled up a ramp by a pull force P. The kinetic friction coefficient between each block and the ramp is µg = 0.40. The blocks start from rėst and speed up the ramp. They reach a speed of 0.85 m/s after 4.00 s. 4.0 kg a) Draw FBDS of both masses. Write down correct NII equations. Find the magnitude of the tension in the string connecting the two blocks. 6.0 kg 30°you need to push the couch 4 m to the other side of the room. After the initial push to get it going you push on the 90 Kg couch with a steady horizontal force of 600 N. The coefficient of kinetic friction between the couch and the floor is 0.6. 1) what is the magnitude and direction of the fictional force on the couch? 2) what is the magnitude and direction of the net force on the couch? 3) what is the magnitude and direction of the acceleration of the couch?
- Question 3 Suppose that the kinetic coefficient of friction between stone and grass is 0.7. A girl is sliding a stone cube (with mass = 8 kg) along the grass with a force of 72 N. What is the net force on the stone? Hint: This problem will require 3 steps! First, find the normal force that the grass is exerting on the stone by setting it equal to the gravitational force that the stone experiences. Next, use that force to calculate the force of kinetic friction as the stone slides. Last, can you find the net force that results from the push vs. the kinetic friction forces??

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.
