a 200 kg bucket of cement is accelerated 2200n. the acceleration continues for 5s, what is the power at the end of the period?

power = 121000 watts or 121 kilowatts

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
