Answer:
“W” will increase four time.
Explanation:
As work done (W) and Kinetic energy (KE) have same units. So, we will deal “W” in terms of “KE”.
KE = ½ mv^2 ……. (i)
Equation (i) shows that KE is directly proportional to the square of speed. So, if speed is increased two time then “W” will increase four time.
