Question

A man of mass 70kg jumps to a height of 50cm. His potential energy will be energy at the highest point is(g = 10 m/s2);
A. 3500J
B. 350J
C. 35J
D. none of these​

Answer 1

Answer:

PE= mgh

M= 70kg

g= 10 m/s^2

h= 50cm= 0.5m

PE= 70×10×0.5

= 70×5

= 350J (B)

Answer 2

★ Question Given :

• A man of mass 70 kg jumps to a height of 50 cm. His potential energy at the highest point is(g = 10 m/s2)

★ Required Solution :

✫ Value Given to us :

• ⇢ Mass of Man = 70 kg

• ⇢ Height jumped up = 0.5 m

• ⇢ g Value = 10 m/s²

✫ Formula Used Here :

• ⇢ Potential Energy = mgh

★ Where :

• ⇢ m = Mass

• ⇢ g = Accelerating due to gravity

• ⇢ h = Height

✫ Putting Value in Formula :

• ⇢ Potential energy = mgh

• ⇢ P. E = 70 × 10 × 0.5

• ⇢ P.E = 350 Joule

✰ Potential Energy is 350 J ✰
