It takes Andy 0.50 seconds to lift a 98-newton box from the floor and place it on the table. If he expends a constant power of 137 watts during this time, what is the height of the table?
Sharkattack123:
We can use the formula W = Fd to find the distance (d) Andy lifted the box, given that we know the force (F) needed to lift the box and want to find the height of the table. Additionally, we know that work done (W) is equal to the power expended (P) multiplied by the time taken (t). Therefore, we can find the work done by Andy during the lifting of the box using this equation. Using the work-energy principle and the formula ΔPE = W = Fd, we can solve for d, which is the height of the table. After plugging in the values, we get that the height of the table is 0.7 meters.
