    Does anyone know how do this question: 1. Student 1 pulls to the left with a horizontal force on a 60 kg crate on a smooth floor. Student 2 pulls to the right on the same crate with a force of 250 N at an angle of 40º above the horizontal. The crate starts from rest and when it has moved 20 m...

    Classical physics: Motion question

    Hey Guys sorry, but do you know if this is right? Question: A car has a final velocity of 26 m/s [N 120 W] after accelerating at 2.5 m/s2 [W] for 4.0 s. Find the initial velocity of the car. Answer: v1 = =aΔt + v2 v1 = -(2.5 X 4) + 26 v1 = -10 + 26 v1 = 16
