A force acts on a mass of 16 g for 3 s and then ceases to act. What the magnitude of the force? |
|
Answer» 144 dynExplanation:While covering the distance of 81 cm, there was no external force on the body and therefore it must have covered this distance with a uniform VELOCITY v, generated when the force was acting on the body.s = vt or, v = `(s)/(t) = (81)/(3) = 27 " cm " cdot s^(-1)`If the acceleration on the body due to force was a then`" "` v = u + at or, 27 = 0 + a`xx`3 or, a = 9 cm `cdot s^(-2)``therefore" "` Applied force, F = ma = 16 `xx` 9 = 144 dyn.hope it is helpful to you mark as BRAINLIEST ... |
