Basketball player Darrell Griffith is on record as attaining a standing vertical jump of 1.2 m. (This means that he moved upward by 1.2 m after his feet left the floor. Griffith weighed 890 N. A-What is his speed as he leaves the floor? B-If the time of the part of the jump before his feet left the floor was 0.300 s , what was the magnitude of his average acceleration while he was pushing against the floor? C-Use Newton's...
to stop a 90 kg basketball player landing from a jump with a downward vertical How much work is required velocity of 3.48 m/s at the point of ground contact? Assume the basketball player has no potential energy, only kinetic energy. (3 points) How much force is required if the basketball player (Question #2) lands with a 'hard' or 'soft' landing? a For 'soft' landing assume the basketball player's center of mass is displaced 0.65 m. (2 point) b....

A basketball player is standing on the floor 100 m from the basket as in the figure below. The height of the basket is H - 3.05 m, and he shoots the ball at an angle, 0-38.0°, with the horizontal from a height of h = 1.84 m. (a) What is the acceleration of the basketball at the highest point in its trajectory? magnitude m/s direction -Solo... (b) At what speed must the player throw the basketbal so that the...
A basketball player attempts a three-point shot 10.0 m from the basket as shown in the figure below. The player shoots the ball at an angle of θ = 38.4° from horizontal, and releases the ball at a height of h 2.16 m. The rim of the basket is at a height of H- 3.05 m 10,0 m (a) What is the acceleration (in m/s2) of the basketball at the highest point in its trajectory? m/s2 magnitude 9.8 direction downward...
You toss a racquetball directly upward and then catch it at the same height you released it 1.28 s later. Assume air resistance is negligible. (a) What is the acceleration of the ball while it is moving upward? magnitude m/s2 direction (b) What is the acceleration of the ball while it is moving downward? magnitude m/s2 direction (c) What is the acceleration of the ball while it is at its maximum height? magnitude m/s2 direction (d) What is the velocity...
A 75-kg volleyball player performs a maximum-effort vertical jump with an initial velocity of 3 m/s. The player leaves the ground with an upright body position and also touches down with the same body position. Answer the following: ua A. How much will the player's center of mass (COM) travel in the air along the vertical direction during the ascending phase of the jump? Compute the maximum kinetic energy of the player during the jump. C. Compute the maximum potential...
A basketball player is running at a constant horizontal speed of 2.5 m/s when he tosses a basketball directly upward with a speed of 6.0 m/s. Ignoring air resistance: a. Determine the magnitude and direction of the basketball’s velocity, initially, when the ball left the player’s hand. b. Determine the vertical displacement of the ball away from the player’s hands. c. Determine the time of flight of the ball given that it returns to the player’s hand at the same...
A 110-kg basketball player can jump a vertical distance of 1.3 meters (approx. 4 feet). For this entire problem, assume that the athlete has NO horizontal motion. (Ignore air resistance.) 6. (2 pts.)

At the moment the athlete reaches his maximum height, which of the following is/are equal to zere?...
A person is initially driving a car east down a straight road. The magnitude of the instantaneous acceleration remains constant with time, and the direction of the acceleration is always to the west. The speed of the car is O decreasing but then increasing O increasing O increasing but then decreasing O constant. O decreasing. While standing at the edge of the roof of a building, you throw a stone upward with an initial speed 7.39 m/s. The stone subsequently...
