A ramp is 2.8m long and 1.2m high. How much power is needed to push a box up the ramp in 4.6s with a force of 96N

P = F * d/t = 96 * 2.8/4.6 = 58.43 J/s =

58.43 Watts.

58

To find the power needed to push the box up the ramp, we first need to calculate the work done.

The work done is given by the formula:

Work = Force x Distance

In this case, the force is 96N, and the distance is the length of the ramp, which is 2.8m.

Work = 96N x 2.8m

Now, we need to calculate the time it takes to do this work. The time is given as 4.6s.

To find the power, we use the formula:

Power = Work / Time

Now let's substitute the values into the formula:

Power = (96N x 2.8m) / 4.6s

Calculating this, we get:

Power = 55.826

Therefore, the power needed to push the box up the ramp is approximately 55.826 watts.

To calculate the power needed to push the box up the ramp, you can use the formula:

Power = (Force * Distance) / Time

1. First, let's calculate the distance. In this case, the distance is the length of the ramp, which is given as 2.8 meters.

Distance = 2.8m

2. Next, let's calculate the time. The time is given as 4.6 seconds.

Time = 4.6s

3. The force needed to push the box up the ramp is given as 96N.

Force = 96N

4. Now we can substitute these values into the formula to calculate the power:

Power = (96N * 2.8m) / 4.6s

Power = 556.69 Watts

Therefore, the power needed to push the box up the ramp is approximately 556.69 Watts.
