Question

1 A particle of mass 100g moves at a speed of 1m/s It's kinetic energy is

Answer 1

Mass(m) =  100 g = 0.1 kg
Speed(v) = 1 m/s

Kinetic energy (KE) = 1/2 mv²
                                = 1/2 × 0.1 kg ×(1 m/s)²
                                = 0.05 Joule

Answer 2

Hello yaar,

Given,
Mass = 100g
=0.1kg

Velocity =1 m/s


Kinetic Energy = 1/2 mv^2
= 1/2 × 0.1 × 1
= 0.05 Joules


Hope it helps u....
