If the mass of a ball is 20g and h is 8m, calculate the kinetic energy when it has a velocity of 2ms raise to power minus 1

Answer 1

h doesn't matter

KE = 1/2 mv^2 = (1/2)(0.02)(2) = 0.02J

all those words are just noise.
v is 2 m/s, much easier to read.

Answer 2

If the mass of the ball is 20g and height is 8m, calculate the kinetic energy when it has a velocity of 2m/s *

Answer 6

Ke -1/2mv^=(1/2)(0.02)(2)=0.02j.
