Question

a body of mass 10 gram is having the kinetic energy of 200J calculate the speed of the body​

Answer 1

Answer:

Mass, m=200gm=0.2kg

K.E=10J

Momentum,P=?

As,  1/2 mv^2 =10

v^2  = 10*2/0.2  =100

v=10ms^−1

 Momentum, P=mv=0.2×10=2kgm/s

I have taken mass 200g and 10J

please mark me as brilliant

Answer 2

Answer:

Velocity = 200

Explanation:

Since we know that Kinetic Energy = 1/2× mv²

We have,

Mass = 10g = 0.01 Kg

Kinetic Energy = 200J

So by applying the equation 1/2 × mv²

We get that,

1/2 × mv² = 200J

1/2 × 0.01 × (v) ² = 200J

v² = 200 × 2 / 0.01

v² = 200 × 100 × 2 / 1

v = √40000

v = 200 m / sec.

I HOPE IT WILL BE HELPFUL FOR YOU.
