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 net (unbalanced) external force of 100.0 N acts on an object of mass 20.0 kg whose initial speed is 10.0 m/s. The force acts in the opposite direction from the object's motion, and it acts for 1.00 s. What is the object's final speed, in m/s?
A 2.0-kg object has a velocity of 4.0i ^ m/s at t = 0. A constant resultant force of (2.0i ^ + 4.0j ^ ) N then acts on the object for 3.0 s. What is the magnitude of the object’s velocity at the end of the 3.0-s interval?

Two blocks (m1=5.2 kg, m2=3.6 kg), initially held at rest, are connected by a string that passes through a massless pulley as shown in the Figure. The block of mass m1 is given a push up the inclined plane, and released with an initial speed of v0 =11.8m/s . Take kinetic friction coefficient between the surface and blocks is µk =0.2, and θ =19.2 0. Find the maximum distance d for the block to move on the inclined plane after being released (just before coming to a stop temporarily). Take g=9.81 m/s2, and express your answer using two decimal places.
