then attach the 5 kg and 10 kg cubes to each other with a cable, and we will raise the ramp so it makes a 20° with the ground. As in the picture below, we place the 5 kg cube on the ramp, and hang the 10 kg cube over a pulley so it is free to fall to the ground. The pulley is very light compared to the cubes so it will have a negligible effect on the motion of the connected cubes. The acceleration is 5.42 m/s^2. b. Same scenario as part a, but now the ramp is made of a smooth material, and the 5 kg cube is on wheels. This creates a coefficient of static friction between the 5 kg cube and the ramp of 0.15. What is the acceleration of the connected cubes? Draw a free-body diagram for each cube
5) a. We then attach the 5 kg and 10 kg cubes to each other with a cable, and we will raise the
ramp so it makes a 20° with the ground. As in the picture below, we place the 5 kg cube on the
ramp, and hang the 10 kg cube over a pulley so it is free to fall to the ground. The pulley is very
light compared to the cubes so it will have a negligible effect on the motion of the connected
cubes. The acceleration is 5.42 m/s^2.
b. Same scenario as part a, but now the ramp is made of a smooth material, and the 5 kg cube is
on wheels. This creates a coefficient of static friction between the 5 kg cube and the ramp of 0.15.
What is the acceleration of the connected cubes?
