Seema knows the mass of a basketball. What other information is needed to find the ball’s potential energy? the volume and heigh
t the ball reaches the volume and shape of the ball acceleration due to gravity and the height the ball reaches acceleration due to gravity and the shape of the ball
Acceleration due to gravity and the height the ball reaches
Explanation:
The potential energy of an object can be determined using its mass and the height of the ball it reaches. It is given by :
Where
m = mass of the ball
g = acceleration due to gravity
h = height reached by the ball
Hence, to find the ball’s potential energy she must know the "acceleration due to gravity and the height the ball reaches". Hence, the correct option is (c).
t is time in s For example, a car accelerates in 5 s from 25 m/s to 3 5m/s. Its velocity changes by 35 - 25 = 10 m/s. Therefore its acceleration is 10 ÷ 5 = 2 m/s2
