Question

A ball of iron mass 1kg is dropped from tbe top of building the ball reaches the groind in 5s what is the velocity in m/s of the ball when it strikes the ground

Answer 1

Answer:

we know that acts velocity is equal tov is equal to u + GT where is zero the value of g is and point 8 and the given time is 5 seconds so we should multiply 9.8 into 5 the final answer will be 49m/ s

Answer 2

Answer:

Explanation:

Ball strike to the ground with 50 m/s

According to equation of motion

V=u+at

Acceleration is 10 =g

u=0
