Six seconds after starting from rest,a freely-falling baseball has a speed of
A)10 m/s.
B)30 m/s.
C)60 m/s.
D)70 m/s.

Question

Quizplus · Accepted Answer

The acceleration due to gravity is approximately 9.8 m/s^2. After falling for 6 seconds, the velocity of the ball can be found using the equation:
v = at, where v is the final velocity, a is the acceleration due to gravity, and t is the time.
Thus, v = (9.8 m/s^2)(6 s) = 58.8 m/s. Rounding to the nearest whole number, the answer is 60 m/s, which is choice C.
