The cart in figure 1 slides in the horizontal plane with an acceleration of 7 m / s². Body A has 7 kg of mass and there is no friction between the body and the support planes. Determine the horizontal force that the vertical wall exerts on the body, considering it in relation to the cart.
I need the answer now please. Thank you. No rounding off in the solutions, only your final answer should be rounded off to 3 decimal places. use g=9.81m/s^2 or g=32.2ft/s^2

4. The system shown at right consists of a frictionless pulley and a rope supporting two masses. Use work and energy methods to determine velocity of each mass just before the 12 kg mass hits the floor. Use that velocity to determine acceleration and draw a FBD (with solved forces) of each pulley while they are in motion. 12 kg 1.5 m 8. kg
