Question

the ball of mass 50g thrown vertically upward with an initial velocity 20 metres per second Max find the High Street in fiction neglected and initial potential energy of the ball

Answer 1

Max height attained = u square/2g
=20*20/2*10
=20m
Initial potential energy =mgh
50*10*20/1000
= 10J

Answer 2

Answer:

Max height attained = u square/2g

=20*20/2*10

=20m

Initial potential energy =mgh

50*10*20/1000

= 10J
