A golf ball is dropped from rest from a height of 9.30 m. It hits the pavement, then bounces back up, rising just 5.80 m before falling back down again. A boy then catches the ball when it is 1.00 m above the pavement. Ignoring air resistance, calculate the total amount of time that the ball is in the air, from drop to catch.
Determine the wave's amplitude. Determine the wave's wavelength. Determine the wave's frequency. Determine the wave's speed of propagation. Determine the wave's direction of propagation.
A humanitarian aid package is dropped from a plane flying horizontally 500m above the ground with a speed 100m/s. What is the speed of the package at time of impact? (Calculate the total speed, not a horizontal or vertical projection.)
A converging lens is placed 20.0 cm to the right of a diverging lens of focal length 7.0 cm. Calculate the focal length of the converging lens

A 8 kg box slides d = 4.2m down the frictionless ramp, after that collides with a spring whose spring constant is 250 N/m. angle is 30 degrees.
An iron cube with a volume of 8.00cm^3 is submerged in ethyl alcohol, which has a density of 0.806g/cm^3. What is the volume of ethyl alcohol displaced
A novice skier, starting from rest, slides down a frictionless 37.0° incline whose vertical height is 175 m. Explain how fast is she going when she reaches the bottom?
If you were standing on a spinning turntable holding barbells close to your chest, how would your spin be affected? Why?
Two blocks are connected by a very light string passing over a massless and frictionless pulley (Fig. E6.7). Traveling at constant speed, the 20.0-N block moves 75.0 cm to the right and the 12.0-N block moves 75.0 CIJl downward.
