Question

a ball of mass 1.5 kg is moving with a speed of 20 metre per second. find its kinetic energy answer is 300 joules show me step by step​

Answer 1

Answer:

300 J

Explanation:

K.E= 1/2 mv²

where m is mass of body and v is velocity of body and K.E represents kinetic energy.

In given statement,

m= 1.5 kg  ,   v = 20 ms-1    and K.E=?

Solution:

K.E = 1/2 × 1.5  × ( 20)²

K.E = 1/2 × 1.5  × 400

K.E = 1/2 × 600

K.E = 300 J.
