5. A basketball with a mass of 2 kg (weight of-19.62 N) has been thrown into the air. At the time of its peak vertical displacement, 3 players made0 SON contact with the ball simultaneously. The forces that each player applies to the ball are indicated on the diagram below. What is the resultant force (and at what angle) acting on the ball? 20 100 N

1. A ball of weight 5.0 newtons is thrown towards the ceiling and hits with the speed shown at an angle = 37° from the vertical. The ball is in contact with the ceiling for 0.1 second. Use cos(37°) = 0.8 and sin(37°) = 0.6 a. Determine the magnitude and direction of the average acceleration of the ball while it is in contact with the ceiling.

Two basketballs, one regulation and one heavy ball (regulation basketball has mass of 0.624 kg while the heavy ball has mass of 1.359 kg are tied to each other by a light string (light string means you need not consider the mass of the string). The regulation ball is above the heavy ball and a player holds the regulation ball in his palm. Draw the free body diagram(s) appropriate for the situation and then calculate the force that the player...

(1) A 4m ladder has mass m= 10 kg. We assume that its centre of mass is half-way along its length. The ladder is leaning against a wall at an angle of 30° from the vertical, as shown in the figure. Suppose that the wall is frictionless smooth and slippery), and that the coefficient of static friction between the feet of the ladder and the floor is H. =0.6. Take the acceleration due to gravity to be g=10m/s" directed vertically...

1.) A ball of mass 0.1kg is thrown straight up with an initial velocity of 19.6 m/s. in answering the following, neglect air resistance and only consider times after the ball has left the hand of the person throwing it. a.) Draw a free-body diagram of the ball indicating the directions and sources of all of the forces acting on it. To indicate sources, it suffices to use appropriate subscripts on the symbol you choose to represent the magnitude of...
