Give 1 examplre of -uniform velocity, variable velocity.
Give 1 example of - variable acceleration,uniform retardation.
what is the si unit of retardation?
a juggler throws balls into air. He throws one whenever the previous one is at its highest point. How high do the balls rise if he throws 'n' balls each second? acceleration due to gravity is g.
differentiate between speed and velocity
A train starts from rest and accelerates uniformly at 2m/s^2 for 10 sec.It then maintains the constant speed for 200 sec. The brakes are then applied and the train is uniformly retarded and comes to rest in 50 sec.Find:(i)maximum velocity reached(ii)retardation in last 50 sec(iii)the total disrance travelled and (iv)the average velocity of the train
what is instantaneous velocity
what is the difference between uniform velocity and uniform speed
a car is moving along a straight road with a uniform accelration . it passes through 2 points P and Q separated by a certain distance with velocity of 30kmph and 40 kmph respectively. what is the velocity of car exactly midway between P and Q .
The acceleration 'a' in m/s of a particle is given by a= 3tsq + 2t + 2, where t is time. if the particle starts out with a velocity v= 2m/s at t =0, then find the velocity at the end of 2sec.
A STONE IS THROWN UPWARDS WITH A SPEED "u" FROM THE TOP OF THE TOWER. IT REACHES THE GROUND WITH A VELOCITY "3u" . THE HEIGHT OF THE TOWER IS ?
A Cyclist goes once round a circular track of diameter 105 meters in 5 min. calculate his speed.
A farmer moves along the boundary of a square field of side 10m in 40s. what wil be the magnitude of displacement of the farmer at the end of 2 min 20 sec from the initial position??
