Acrate on a motorized cart starts from rest and moves with a constant eastward acceleration ofa= 2.60 m/s^2. a worker assists the cart by pushing on the crate with a force that is eastward andhas magnitude that depends on time. according to f(t) = (5.40 n/s)t. what is the instantaneouspower supplied by this force at t= 4.70 s

To obtain the power, we first need to find the work made by the force.

1) To calculate the work, we need the next equation:

So the force is given by the problem so our mission is to find 'dx' in terms of 't'

2) we know that:

So we have:

Then:

3) Finally, we replace everything:

After some calculation, we have as a result that the work is:

161.9638 J.

4) To calculate the power we need the next equation:

So

P = 161.9638/4.7 = 34.46 W

d) physical means can be used to separate the components of air.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
