Question
A rock is thrown vertically into the air. Ignore air resistance. At the top of its path, the
acceleration acting on it is:
A) increasing
B) zero
C) decreasing
D) a constant value (10 m/s2)
To produce an acceleration to a body, there
A) May or may not be a net force acting on the body
B) Must NOT be a net force acting on the body
C) Must be a net force acting on the body
D) Must be acceleration outside the body also.
Expert Solution
Step 1
We know that the rock is thrown vertically and the air resistance is being ignored.
