Question
A 2 kg toy car can move along an x axis. Graph shows force Fx, acting on the car which begins at rest at time t = 0. The velocity of the particle at t = 10 s is :
Options
A.- i m/s
B.-1.5 i m/s
C.6.5 i m/s
D.13 i m/s
Solution
= pf − pi = 
= Area under the curve.pi = 0
Net Area = 16 − 2 − 1 = 13 N -s
Vf =
= 6.5 i m/sCreate a free account to view solution
