Question

A body mass is moving with a velocity 5m/sec its kinetic. energy is 25j . if its​

Answer 1

Answer:

velocity =5 m/s

mass = ?

we know that... kinetic energy(E)= 1/2 × mass × (velocity)²

• so... E = 1/2 mv²
• 25 =1/2 × m × (5)²
• 25 = 1/2 × m × 25
• 25m = 50
• m = 50/25
• m = 2

so... body mass = 2 kg
