Question

A body of mass 5 kg is thrown vertically upwards with an initial velocity of 20m/s. Calculate its K.E. and P.E. after 2 seconds. (Take g=10m/s)​

Answer 1

Answer:

Explanation:

M= 0.1, V= 10m/s, g=10m/s^2

Total Engergy = K.E + P.E

i.e::: 1/2mv2 + mgh = Total Energy.

by inputin d values, we have,

1/2×0.1x10^2 + 0.1x10x10

= 5 + 10, i.e 15J.
