Answer:
20000 W
Explanation:
Power: This can be defined as the rate at which energy is dissipated or used. The S.I unit of power is Watt(W).
The expression of power is given as,
P = E/t.............................. Equation 1
Where P = power, E = Energy, t = time.
Given: E = 200 J, t = 0.01 s
Substitute into equation 1
P = 200/0.01
P = 20000 W.
Hence the average power = 20000 W

centripetal acceleration can be determined using the following equation;
a = v² / r
a= centripetal acceleration
v = velocity
r = radius
substituting the values in the equation,
a = (300 m/s)*(300m/s) / (1.85 *1000) m
= 48.64 ms-²
