Question

1 . A 10. kg ball is thrown into the air it is going 3.6 ms when thrown . how much potential energy it has on top​

Answer 1

Answer:

we know 2as=v²-u²

here a=-9.8m/s²

and v= 0

so, 2(-9.8)s= -(3.6)²

-19.6s= -12.96

s = 12.96/19.6

s or h = 0.66 m

and we know that potential energy =mgh

10*9.8**0.66

= 64.68 J
