Hello, can you please help me with this physics question? A ball with a mass of 0.17 kg is bounced off a tenis court. Before hiting the ground, the ball is moving at a velocity of (1.4, -8.5)m/s. If the ground exerts a force of 203 N acting upward for a time of 0.0125s, what is the final velocity of the ball leaving the ground of the tenis court? (the y value is positive in the upward direction)
An object of mass ?=8.9 kg is free to move on a horizontal surface without any friction. It is initially at rest and starts moving under a net force of ?⃗=(3 N)?̂+(4 N)?̂. What is the object's speed in m/s after moving 1 meter?
