A 5kg model vehicle traveling at 14 m/s experiences a rocket boost of 85N (in the direction of motion) for 20s. What is the resulting speed?
I tried using:
F = mv/t, but that didn't work out for me.
85 = 5v/20
85*20 = 5v
1700/5 = v
v = 340 m/s
but, that's wrong... what am I doing incorrectly? thanks.
edit: I guess you could consider impulse actually, heh... whoops
