Question

If the speed of a particle is doubled, what will be the new kinetic energy

Answer 1

Heya mate,Here is ur answer

Kinetic energy= 1/2× mv^2

when speed is doubled, v =2v

$k.e. = \frac{1}{2} \times m \times {(2v)}^{2}$

$k.e. = \frac{1}{2} \times m \times 4 {v}^{2}$

$k.e. = 4 \times \frac{1}{2} \times mv {}^{2}$

$k.e.=4×Previous\: kinetic\: energy$

$<b><u>So, Kinetic energy will increase by 4 times when speed is doubled.</u></b>$
