A constant power P is applied to a car starting from rest. If v is the velocity of the car at time t, then:

Engine of car of mass m supplies a constant power P. Starting from rest at an instant of time, then

Engine of car of mass m supplies a constant power P. Starting from rest at an instant of time, then

A car of mass M accelerates starting from rest. Velocity of the car is given by v=((2Pt)/(M))^((1)/(2)) where P is the constant power supplied by the engine. The position of car as a function of time is given as

A car is moving on a straight road. The velocity of the car varies with time as shown in the figure. Initially (at t=0), the car was at x=0 , where, x is the position of the car at any time 't'. The maximum displacement from the starting position will be :-

A car moves in a straight line, the car accelerates from rest with a constant acceleraation alpha on a straight foad. After gaining a velocity v , the car moves with that velocity for somerime. Then car decelerates with a retardation beta , If the total distance covered by the car is equal to s find the total time of its motion.
