2 answers:
Answer:
The work done and power are 60000 Pounds-feet and 3000 Pounds-feet/sec.
Explanation:
Given that,
Force F = 1500 pounds
Distance d = 40 feet
Time t = 40 sec
Work done :
The work done is the product of the force and distance.
The work done is defined as,
Where, W = work
F = force
d = distance
Put the value into the formula of work
Power:
The power is equal to the work done divided by time.
The power is defined as,
Where, P = power
W = work
t = time
Put the value into the formula of power
Hence, The work done and power are 60000 Pounds-feet and 3000 Pounds-feet/sec.
