(Express your answer in vector form.) a = m/s? (b) What are the magnitude and direction of the acceleration? magnitude m/s? direction counterclockwise from the +x axis

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)

A toy rocket engine is securely fastened to a large puck that can glide with negligible friction over a horizontal surface, taken as the xy plane. The 5.80-kg puck has a velocity of 2.001 m/s at one instant. Eight seconds later, its velocity is (6.001 + 8.0ĵ) m/s. (a) Assuming the rocket engine exerts a constant horizontal force, find the components of the force. Î + (b) Find its magnitude. N

A 0.697 kg football is thrown upward with an initial speed of 49.7 m/s.  Neglecting wind resistance, what is the force on the ball when it reaches half its maximum height? Use g=9.8 m/s

A worker pushes a 35.0-kg package on a horizontal roller-belt conveyor until it reaches a certain speed. The package then coasts on the horizontal conveyor, all the while slowing down, until it comes to a complete stop after moving 1.20 m. While the package is coasting on the conveyor, the opposing friction force averages 6.00 N. Use the WET to find the speed of the package after the worker pushes it and just as it begins to coast. 0.625 m/s 0.759 m/s 0.600 m/s 0.510 m/s 0.802 m/s 0.641 m/s

A 5.25 • 105-kg rocket is accelerating straight up. Its engines produce 1.05 • 107 N of thrust, and air resistance is 4.5 • 106 N . What is the rocket’s acceleration, using a coordinate system where up is positive?

While walking on water, an arctic wind freezes the water beneath your feet and you now find yourself stuck in the middle of a 15m diameter lake on top of a frictionless layer of ice.  Unable to just walk off, you decide to push off your physics book with a force of 80.0N for 0.1s.  How long in minutes will it take you to reach the shore if your mass is 75kg?
