A basketball star covers 2.80 m horizontally in a jump to dunk the ball (Fig. P4.12a). His motion through space can be modeled precisely as that of a particle at his center of mass, which we will define in Chapter 9. His center of mass is at elevation 1.02 m when he leaves the floor. It reaches a maximum height of 1.85 m above the floor and is at elevation 0.900 m when he touches down again. Determine (a) his time of flight (his hang time), (b) his horizontal and (c) vertical velocity components at the instant of takeoff, and (d) his takeoff angle. (e) For comparison, determine the hang time of a whitetail deer making a jump (Fig. P4.12b) with center of mass elevations yi = 1.20 m, ymax = 2.50 m, and yf = 0.700 m. Figure P4.12
Professional Application Using mass and speed data from Example 8.1 and assuming that the football player catches the ball with his feet off the ground with both of them moving horizontally, calculate: (a) the final velocity if the ball and player are going in the same direction and (b) the loss of kinetic energy in this case. (c) Repeat parts (a) and (b) for the situation in which the ball and the player are going in opposite directions. Might the loss of kinetic energy be related to how much it hurts to catch the pass?
A 2.00 1O3-kg car moving cast at 10.0 m/s collides with a 3.00 103-kg car moving north. The cars stick together and move as a unit after the collision, at an angle of 40.0 north of east and a speed of 5.22 m/s. Find the speed and direction of the 3.00 103-kg car before the collision.
Repeat the preceding problem if the balls collide when the center of ball 1 is at the origin and the center of ball 2 is at the point (3R/2,R/2) .
A baseball approaches home plate at a speed of 45.0 m/s, moving horizontally just before being hit by a bat. The batter hits a pop-up such that after hitting the bat, the baseball is moving at 55.0 m/s straight up. The ball has a mass of 145 g and is in contact with the bat for 2.00 ms. What is the average vector force the ball exerts on the bat during their interaction?
Ball B is hanging from a cord of negligible weight. An identical ball A is measured 3m above the hanging ball and just touching the cord, is released from rest and acquires a velocity (V_o) before striking ball B. Assuming perfectly elastic impact and no friction, compute the A) magnitude of the velocity of ball A in terms of V_o or velocity before impact B.) direction of the velocity of ball A in terms of V_o or velocity before impact (note: should be in angle with respect to north, east, west, south)
After falling from rest from a height of 30-m, a 0.50-kg ball rebounds upward, reaching a maximum height of 20-m. If the contact between the ball and the ground lasted 20 milliseconds, what average force was exerted on the ball by the ground? (Hint: consider the change in velocity that has occurred between the interval just before and just after hitting the ground). Answer: 1.1 x 10^3 N
A 4kg ball and a 3 kg ball move on a smooth horizontal plane along a straight-line path with speed of + 6 and -8m/s respectively. Determine the following: a) Speed of the 3kg ball after impact if the impact is inelastic or plastic b) Speed of the 3kg ball after impact if the impact is elastic or plastic c) Speed of the 3kg ball after impact if the coefficient of restitution e = 005
A rocket of initial mass 1000 kg adjusts its thrust by varying the rate of mass ejection. The ejection speed relative to the rocket is 40 km / s. If the acceleration of the rocket must have a magnitude of 20 m / s2 at an instant when its mass is 80% of the original mass, at what rate is it being ejected at this instant? Ignore any forces external to the rocket.
A child in a boat throws a 5.50-kg package out horizontally with a speed of 10.0 m/s. The mass of the child is 26.6 kg and the mass of the boat is 36.4 kg. Calculate the velocity of the boat immediately after, assuming it was initially at rest.Express your answer to three significant figures and include the appropriate units. Enter positive value if the direction of the velocity is in the direction of the velocity of the box and negative value if the direction of the velocity is in the direction opposite to the velocity of the box.
The average thrust created by the first stage engine of a model rocket is 50N. The rocket has an average weight of 10N with a burn time of 2 seconds. The rocket is initially fired vertically upward. When the rocket reaches maximum height, a second engine is fired creating a horizontal velocity (only) of 50m/s. Where does the rocket land relative to its launch point? Assume it was launched on a horizontal plain.
