A body mass 6kg moving with a speed of 3m/s is acted on by a force of 18N For 4s. Find the speed of the body
Answered by Ama
Pls solve it
Answered by oobleck
F = ma, so a = 18/6 = 3
You don't say whether the force is acting with its motion or against it, so I'll just say
v = 3 + at = 3 ± 4*3
so decide which, and either add or subtract the 12 m/s
