A 100 kg mass is acted upon by a force given by 16 5x, Ask an Expert

Academics

a 10.0 kg mass is acted upon by a force given by (16 + 5x -4x^2)(i), where x is measured in meters.

(a) How much work is done by this force as the mass moves from x=0 to x=+3m.

(b) If the mass is released from rest at x=0, what will be its velocity when at x=2m/.
