Question: A constant horizontalforce of 250 N acts for adistance of 36 m on a 500 kgbox. If friction is neglected andthe box starts from rest, what isits velocity? |

Answer» Explanation: Work F = ma 250= 500 × a a =0.5m/s^2 We KNOW that, v^2 = u^2 + 2as v^2 = 0 + 2 × 0.5 × 36 【initially body was at rest , u=0】 【distance travelled = 36m, s= 36m】 v^2 = 36 v = +- 6 |v| = 6m/s MARK ME AS BRAILIESTF O L L O W ME |
