Work and Kinetic Energy ve Work and Kinetic Fnergy O Practice Probl IIITIIIITIITTIITTIITITIIITIT O Learning Goal Pro Learning Goals A 5 kg box is being pulled across a rough horizontal loor by a rope with constant tension of T 8N. A frictional force is opposing the movement with Fy 3N. The box is being pulled and as a result its speed is increasing from 0.9 m/s to 1.7 m/s. Find the distance traveled during this period. Pick the correct answer 0.65 m None of these are correct 2.08 m 0.47 m 1.04 m cbojobo

Explanation / Answer

Net force on block

F= 8-3

5a= 5

a= 1 m/s^2

Using 3rd equation of motion

s= (v^2-u^2)/(2a)

= (1.7^2-0.9^2)/(2*1)

= 2.08 m (ans)
