Question

u) Calculate the acceleration that the box will experience if it weighs 20 kg. Problem 2 (A Force + Motion Problem) 4.7 of text: A 68.5 kg skater moving initially at 2.40 m/s on rough horizontal ice comes to rest uniformly (with constant acceleration) in 3.52 s due to friction from the ice. What force does friction exert on the skater?

Step 1

Given: Initial velocity (u) = 2.40 m/s Final velocity (v) = 0 m/s (since the skater comes to rest) Time (t) = 3.52 s We can use the equation of motion: v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the Show more…
