Question

At a certain point K.E and P.E of a body of mass 0.1kg moving vertically up are 3.6J And 6.2J. It rises to a maximum height of

Answer 1

At the given point

the P.E= 6.2 J and K.E=3.6 J

Total energy= K.E+P.E= 6.2+3.6= 9.8 J

for maximum height the total energy should be equal to its potential energy

⇒mgh = 9.8

⇒h=9.8/mg = 10m
