Question

11-f speed of a car becomes
2
times, its kinetic energy
becomes *
O a) 4 times
O (b) 8 times
O (c) 16 times
0 (d) 12 times

​

Answer 1

Answer:

36

Explanation:

Kinetic energy is mathematically defined as K.E =

2

1

mv

2

Hence kinetic energy is directly proportional to the square of the velocity. Thus if we increase the speed of a motor by 6 times then the kinetic energy becomes 36 times.
