Solve the momentum for each of the following moving objects: A. a 0.50kg basketball that is thrown upward with a velocity of 300 m/s. B. A 2000 kg light railway cart moving in the direction of south with a velocity of 10m/s

Consider two sleds that are connected by rope. The first sled has a mass of 60kg, while the second sled has a mass of 40kg. If a force of 250 N acting to the first sled, determine the acceleration of the sled and the tension in the rope connecting two sleds.

What is the applied force needed on 2.0 kg block of wood accelerating at 4.0m/s^2 along rough table with a 10 N force of friction acting in the opposite direction?

What is the acceleration of bowling ball with a mass of 50.0 kg if a net force of 20 N is acting on it?

Verify the net force's magnitude and direction for each of the following problem. Illustrate by making a free body diagram and recognize in which case the object could be at rest. A.3.0 Newton [West] and 4.0 Newton [East] B. 2.0 Newton [North], 3.0 Newton [West],5.0 Newton [East], and 2.0 Newton [West] C. 2.0 Newton [North], 2.0 Newton [East], 3.0 Newton [West], 1.0 Newton [East], and 2.0 Newton [South]

A man observing from an upper floor of a building sees a boy looping a ball in a cord. If the cord breaks, what path will the ball take? Explain your answer.

An athlete executing a long jump leaves the ground at a 28.0 angle and travels 7.80 m. (a) What was the takeoff speed? (b) If this speed were increased just 50%, how much longer would the jump be?

A hunter aims directly at a target (on the same level) 75.0 m away. (a) If the bullet leaves the gun at a speed of 180 m/s, by how much will it miss the target? (b) At what angle should the gun be aimed so as to hit the target?
