Question

The haystack maker tractor lifted 120 kg of grass to a height of 5 meters in 6 seconds. Calculate the power of the haystack maker mechanism (g = 10m / san ^ 2)

Please help me,ASAP ! PLEASE

Answer 1

1000 Joules per second.

Step-by-step explanation:

To lift that much grass 5 meters higher than it was before the tractor did work that is the product of the (force needed to overdo gravity) and (displacement):

`W = mg\Delta h=120kg\cdot 10(m)/(s^2)\cdot 5m = 6000J`

Power is work over the amount of time:

`P = (W)/(\Delta t)=(6000J)/(6 s) = 1000 (J)/(s)`
