Answer:

The kinetic energy is 303178 Joule

Explanation:

We must change the speed units to m / s =

1km ---- 1000meters

1h ----- 3600 seconds

v = (95km 1000m / km) / (1h x 3600s / h) = 26, 4 m / s

We use the Kinetic Energy formula: Ec = 1/2 m x v ^ 2

Ec = 1/2 x 870 kg x (26, 4) ^ 2 = 303177, 6 Joule
