A ball is thrown down vertically with an initial speed of 31 ft/s from a height of 44 ft. (a) What is its speed just before it strikes the ground? (b) How long does the ball take to reach the ground? What would be the answers to (c) part a and (d) part b if the ball were thrown upward from the same height and with the same initial speed ? Before solving any equations, decide whether the answers to...

Two objects are allowed to fall from the same height to the ground. They both start from rest at the same time. One is just released and falls straight downward. The other is placed on a frictionless inclined plane that makes an angle of θ with the horizontal. Which one hits the ground with the highest speed? Ignore air resistance. Group of answer choices You need the angle of the incline to determine the answer. The object that falls straight...

Consider a solid sphere of mass m and radius r being released
from a height h (i.e., its center of mass is initially a height h
above the ground). It rolls without slipping and passes through a
vertical loop of radius R.
a. Use energy conservation to determine the tangential and
angular velocities of the sphere when it reaches the top of the
loop.
b. Draw a force diagram for the sphere at the top of the loop
and write...

A solid sphere is released from the top of a ramp that is at a
height h1 = 1.90 m. It rolls down the ramp without slipping. The
bottom of the ramp is at a height of h2 = 1.49 m above the floor.
The edge of the ramp is a short horizontal section from which the
ball leaves to land on the floor. The diameter of the ball is 0.12
