A particle starts with initial speed u and retardation a to come to rest in time T. The time taken to cover first half of the total path travelled is

A body starts from rest and travels with uniform acceleration the time taken by the body to cover the whole distance is t. Then the time taken the body to cover the second half of the distance is

A particle starts with an initial velocity u towards + x direction with an acceleration a after time t_(1) , it starts retarding with another acceleraation a' , comes to an instantaneous stop and returns. If reaches its initial position at time t_(2) . Draw the approximate time dependence plots for particle's displacement and velocity.

Two particles A and B starts from rest and move for equal time on a straight line. The particle A has an acceleration a for the first half of the total time and 2a for the second half. The particle B has an acceleration 2a for the first half and a for the second half. Which particle has covered larger distance?

A car, starting from rest, accelerates at the rate f through a distance s, then continues at constant speed for time t and then decelerates at the rate f/ 2 to come to rest. If the total distance travelled is 15 s, then

A car, starting from rest, accelerates at the rate f through a distance s, then continues at constant speed for time t and then decelerates at the rate f/ 2 to come to rest. If the total distance travelled is 15 s, then

A car, starting from rest, accelerates at the rate f through a distance s, then continues at constant speed for time t and then decelerates at the rate f/ 2 to come to rest. If the total distance travelled is 15 s, then

A particle start revolution with initial speed u in a circular path of radius R. During revolution it is retarded due to friction and its acceleration is given as a = cv^(2) . Find the speed of the particle after completing one revolution.

A particles starts from rest and has an acceleration of 2m//s^(2) for 10 sec. After that , it travels for 30 sec with constant speed and then undergoes a retardation of 4m//s^(2) and comes back to rest. The total distance covered by the particle is
