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:
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.
