The cart in the figure is attached to special spring that can stretch and compress equally well. The spring is very light. The cart and spring rest on a low-friction horizontal surface. The cart is pulled to position I and then released. It moves to position V where it then reverses direction again to position I. A) Draw a force diagram for point I, cart moving right B)Draw a force diagram for point III, cart moving right

James pulls a 1.8 kg dynamics cart up a ramp that is inclined 25o to the horizontal. 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?

After being release from rest, the objects move. When the blocks have moved 1 meter, calculate the speed of the blocks. 2.6 m/s 1.7 m/s 4.4 m/s 2.9 m/s 3.6 m/s
A 1490 N crate is resting on a table connected to a 400 N block through a frictionless pulley system as shown. Friction between the crate and the table is enough to keep the system at rest. The arrows show the forces that act on the crate and the block.
Hello i need to find the coefficient of kinetic friction from this problem. THIS IS NOT A GRADED QUESTION. its a problem from my book im trying to understand. Thank you.
Draw diagram or sketch to help you understand the situation. A 73kg runner starts walking at 3.4 m/s [E] and begins to speed up for 6.0 s, reaching a final velocity of 11.2 m/s [E]. Calculate the net force acting on the runner.
Help with the following question
Alice and Bob had car trouble. Their car broke down and Bob could not restart it. Alice got out to push the car and after some time she asked Bob if he would trade jobs with her for a while. Bob answered, "It won't matter if I do. I took physics, and I know that no matter how hard I push on the car, it will push back on me just as hard so I won't accomplish anything. That's Newton's Third Law and it is always true. It has been tested millions of times. It wouldn't matter if I pushed the car. I wouldn't be able to push it anywhere." Aside from the fact that his relationship with Alice is probably fınished, which of the following correctly explains a flaw in Bob's logic? The third law says that the two forces he is talking about are only approximately equal. The third law does not apply in this case because the car is on wheels. O The two forces he is talking about are on two different objects. Thw two forces will not be the same because the two masses are different. The third law only…
