Astudent is pushing a 50 kg cart, with a force of 600 n. another student measures the speed of the cart, and finds that the cart is only accelerating at 3 m/s^2. how much friction must be acting on the cart?

Explain vector addition, triangle method and parallelogram method

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.
