A particle of mass `m` is at rest the origin at time ` t= 0 ` . It is subjected to a force ` F(t) = F_(0) e^(-bt)` in the `x` - direction. Its speed ` v(t)` is depicted by which of the following curves ?

A particle of mass m is at rest at the origin at time t=0 It is subjected to a force F(t)=F_(0)e^(-bt) in the X-direction. Its speed V(t) is depicted by which of the following curves

A block of mass 2 kg is free to move along the x -axis. It at rest and from t = 0 onwards it is subjected to a time-dependent force F(t) in the x direction. The force F(t) varies with t as shown in the figure. The kinetic energy of the block after 4.5 seconds is

A block of mass 2 kg is free to move along the x-axis it is at rset and from t=0 onwards it is subjected to a time dependent force F(t) in the x-direction The force F(t) varies with t as shown in the figure The kinetic energy of the block after 4.5 seconds, is:

At t = 0 aparticle of mass m start moving from rest due to a force vecF = F_(0) sin (omega t)hati :
