Answer:
<h2>507 J</h2>Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>507 J</h3>Hope this helps you
A solid sphere is placed on a frictionless floor in a very long corridor and is given a quick push so that it begins to slide, w
ithout rotating, along the corridor. How would the angular speed of the sphere be changing if the floor were not frictionless?
A.) It would remain zero because the net torque is still zero.
B.) It would remain zero because the angular momentum is conserved.
C.) It would be increasing until the slipping between the sphere and the floor stops.
D.) It would be increasing until the linear and the angular speeds become equal.
E.) It would be increasing until the translational motion stops.
A.) It would remain zero because the net torque is still zero.
