Question

A body of mass 0.5kg is thrown vertically upwards
from the ground with an Initial velocity of 80.m/s
Calculate
" the potential energy at B 80.0cm above the ground​

Answer 1

Here's the solution,

we know,

potential energy = mgh

where,

• m = mass = 0.5 kg
• g = acc due to gravity = 9.8 m/s²
• h = height = 0.8 m (80 cm)

So,

=》

$p.e = 0.5 \times 9.8 \times 0.8$

=》

$p.e = 3.92 \: \: joules$
