Question

the kinetic energy of an object of mass M moving with a velocity of 5 metre per second is 25 jewels what will be its kinetic energy when its velocity is doubled what will be its kinetic energy when its velocity is increased to 3 times​

Answer 1

Answer:

Good question

Explanation:

your ans =

Given, velocity of object ,v =5ms−1;

kinetic energy of an object ,EK =25J

EK= 1/2mv^2 or 25=1/2×m×(5)^2

or m=50/25=2kg

When the velocity triples,

EK= 1/2mv^2=1/2×2×(15)^2=225J
