Atrunk of mass 22 kg is on the floor. the trunk has a very small initial speed. the acceleration of gravity is 9.8 m/s 2 .what constant horizontal force pushing the trunk is required to give it a velocity of 10 m/s in 20 s if the coefficient of sliding friction between the trunk and the floor is 0.51? answer in units of n.

Explanation:

Given the information from the exercise we need to use Newton's Laws to solve it

If we analyze the y-axis

∑

Since the trunk is moving in the x-axis and its velocity is changing with time, its acceleration is:

Knowing that we can analyze the forces acting in the horizontal direction

∑

So, the force required to push the trunk is 120.96 N
