Figure 5.16 shows the position-time graph of a particle of mass 4 kg. What is the (a) force on the particle for t<0,t>4s,0<t<4 s? (b) impulse at t = 0 and t = 4 s? (Consider one-dimensional motion only).
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:
