Answer:
Answer:
mass of package, m = 3 kg
Explanation:
initial position,
Final position,
time, t = 11 s
Force,
Work done,
where, d = r2 - r1
W =
W = 104.8 J
Power = Work / time
P = 104.8 / 11 = 9.53 Watt
Explanation:
Answer:
7142.86W
Explanation:
Given parameters:
Work done by brake = 40000J
Time taken = 5.6s
