Question

A body of mass 0.5kg is thrown vertically upwards

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,

=》

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

=》

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

Answer 2

Answer:

Okay so we know that

M=0.5 kg

G=9. 8 m/s²

H= 0.8 m

P.e =0.5 x9. 8 x0.8

P.e =3. 92 joules

Hope it helps
