Question

A sled is being pulled along a horizontal surface by a horizontal force Fvec of magnitude 600 N. Starting from rest, the sled speeds up with acceleration 0.08 m/s² for 1 minute.

Find the instantaneous power p created by the normal force at t=10s . the magnitude of the acceleration due to gravity is g=9.8m/s² .

Answer 1

The instantaneous power created by the normal force at t=10s is zero because there is no vertical force, and thus, no work is done by the normal force.

Step-by-step explanation:

To find the instantaneous power created by the normal force at t=10s, we need to calculate the normal force at that time. Since the sled is being pulled horizontally, the normal force will be equal to the weight of the sled. The normal force can be calculated using the equation:

Normal force = mass x acceleration due to gravity

Since the sled is being pulled with a horizontal force, there is no vertical acceleration and the normal force remains constant.

Therefore, the instantaneous power created by the normal force at t=10s is zero because there is no vertical force, and thus, no work is done by the normal force.
