Question

The linear momentum of a body is numerically equal to the kinetic energy of the body. What is the velocity of
the body
a)
$1 \div \sqrt{2} units$
b)2units
c)
$1 \div \sqrt{3} units$
d)
$\sqrt{3} units$
​

Answer 1

Answer:

Ans : The velocity of the body 2units

Answer 2

Answer:

b.2 units

Explanation:

According to the problem

linear momentum = kinetic energy

mv = mv^2÷2

m = mv/2

v/2 = 1

v = 2 units
