Question

A boy of mass 40 kg climbs up a vertical height of 200cm calculate its potential energy

Answer 1

Answer:

800J

Explanation:

Given

• m= 40kg
• h = 200cm = 2m
• g = 10m/s²

To Find

Potential Energy

Solution

P.E. = mgh

P.E. = (40mKg)(10 m/s²)(2m)

P.E. = 800 Kg m²/s²

P.E. = 800J

Answer 2

$\bf \huge \underline { Answer:-}$

784 J

$\bf \LARGE \underline {Given:-}$

Mass (m) = 40kg

Height (h) = 200 cm

Gravitational Force (g) = 9.8 m/s²

______________________________

$\bf \LARGE \underline {To \; Find:-}$

Potential Energy

______________________________

$\bf \LARGE \underline {Solution:-}$

→Convert Height in meter by dividing it by 100

➭ Height (h) = 200/100

➭ Height (h) = 2 m

______________________

We have formula of Potential Energy :-

${\LARGE{\mathbf{\star{\boxed{\boxed{\blue{P.E \: = \: mgh}}}}}}}$

_______________[Put Values]

P.E = 40 × 9.8 × 2

P.E = 80 × 9.8

P.E = 784 J

${\LARGE{\mathbf{\star{\underline{\boxed{\red{P.E \: = \: 784 \: J}}}}}}}$

$\rule{200}{2}$
