The formula is P = E/t, where P means power in watts, E means energy j , and t means time in seconds. This formula states that power is the consumption of energy per unit of time.
P = 15 M / 10*60
M = mega = 10⁶
15 *10⁶ / 600
= 25000 watt
The net force would be 75N - 34N = 41N
The crates rate of acceleration would be 41N=8.5*a so a = 4.8m/s^2
