Answer:
power = 121000 watts or 121 kilowatts
Step-by-step explanation:
power is the rate at which work is done. The expression for power is defined mathematically as follows.
power = work/time
where
work = force × displacement
power = (force × displacement)/time
power = force × displacement/time
recall
velocity = displacement/time. Therefore,
power = force × velocity
mass of cement = 200 kg
Force = 2200 Newton
acceleration = ?
Force = mass × acceleration
2200 = 200a
divide both sides by 200
a = 2200/200
a = 11 m/s²
We need the velocity to calculate for power.
v = u + at
where
u = initial velocity
v = final velocity
a = acceleration
t = time
u = 0 m/s
a = 11 m/s²
t = 5 s
v = u + at
v = 0 + 11 × 5
v = 55 m/s
power = force × velocity
power = 2200 × 55
power = 121000 watts or 121 kilowatts
