A member of the basketball team jumps straight up and their center of mass has a speed of 3.74 m/s as they leave the court. How high above this point is their center of mass at the following times? (Enter your answers in m. Ignore the effects of air resistance, and assume the initial height of their center of mass is at
y = 0.)

The center of mass moves with constant acceleration when constant forces act on the object. A gymnast jumps straight up, with her center of mass moving at 5.25 m/sas she leaves the ground. How high above this point is her center of mass at the following times? (Ignore the effects of air resistance, and assume the initial height of her center of mass is at y = 0.) (a) 0.100 s m (b) 0.200 s m (c) 0.300 s m (d) 0.500 s m
A dolphin in an aquatic show jumps straight up out of the water at a velocity of 14.3 m/s. The magnitude of the gravitational acceleration g = 9.8 m/s2 Take the water surface to be y0 = 0. Choose UPWARD as positive y direction. Keep 2 decimal places in all answers. (a) How high (what maximum height) in meters does his body rise above the water? To solve this part, first note that the body's final velocity at the maximum...

A spring-loaded launcher is used to shoot a ball of mass 1.50 kg straight up in the air, as shown in (Figure 1). The spring has spring constant k 667 N/m. If the spring is compressed a distance of 25.0 centimeters from its equilibrium position y = 0 and then released, the ball reaches a maximum height hmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the...
