Preeti reached the metro station and found that the escalator was not working.
If a car at accelerates uniformly to a speed of 144 km/h in 20 s, it covers a distance of
Question is mentioned below :
If the velocity of a particle is v = At + Bt2, where A and B are constants, then the distance travelled by it between 1 s and 2 s is
A small block slides down on a smooth in cleaned plane, starting from rest at time t = 0.
Question is mentioned below :
A person travelling in a straight line moves with a constant velocity v_1 for certain distance ‘x’ and with a constant velocity v_2 for next equal distance. The average velocity v is given by their relation
A car moves a distance of 200 m. It covers the first half of the distance at speed 40 km/h and the second half of distance at speed v. The average speed is 48 km/h. The value of v is
A car covers the first half of the distance between two places at 40 km/h and another half at 60 km/h. The average speed of the car is
A bus travelling the first one-third distance at a speed of 10 km/h, the next one-third at 20 km/h and at last one-third at 60 km/h. The average speed of the bus is
