The kinetic energy K of a moving object varies jointly with its mass M and the square of the velocity V. If an object weighing 34 kilograms and moving with velocity of 10 meters per second has a kinetic energy of 1,700 joules, find its kinetic energy when the velocity is 19 meters per second

Answer:

6137 J

Step-by-step explanation:

K is proportional to M and V²:

K = c MV², where c is a constant.

When M = 34 and V = 10, K = 1700.

1700 = c (34) (10)²

c = 0.5

When M = 34 and V = 19:

K = 0.5 (34) (19)²

K = 6137
