A ball is thrown straight up with an initial speed of 36 m/sm/s .

Find a height that the ball will reach mm (neglecting air resistance).

A force F acts in the forward direction on a cart of mass m. A friction force f opposes this motion.

Use Newton's second law and express the acceleration of the cart.

If the cart's mass is 3.4 kgkg , the applied force is 12.6 NN , and the friction force is 5.8 NN , find the cart's acceleration.

If you stand next to a wall on a frictionless skateboard and push the wall with a force of 44 NN , how hard does the wall push on you?

If your mass is 86 kgkg , find your acceleration.
