Atennis ball is dropped from a height of 10.0 m. it rebounds off the floor and comes up to a height of only 4.00 m on its first rebound. (ignore the small amount of time the ball is in contact with the floor.) (a) determine the ball’s speed just before it hits the floor on the way down. (b) determine the ball’s speed as it leaves the floor on its way up to its first rebound height. (c) how long is the ball in the air from the time it is dropped until the time it reaches its maximum height on the first rebound?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
