Question

A cyclist and bike have a total mass of 100 kg and a speed of 15 m/s. Calculate the kinetic energy.​

Answer 1

Explanation:

$kinetic \: energy \: = \frac{1}{2} \times m \times {v}^{2}$

$\frac{1}{2} \times 100 \times {15}^{2}$

$50 \times 225 = 11250$

THIS IS UR ANSWER AND PLS MARK ME THE BRAINILIST

Answer 2

Explanation:

Kinetic energy =1/2mv square

1/2*100*15*15=50*225=11250
