A jet aeroplane travelling at the speed of 500 km/h ejects the burnt gases at the speed of 1200 km/h relative to the jet aeroplane. Find the speed of the burnt gases w.r.t. a stationary observer on earth.

A car start from rest and acquire a velocity of 54 km/h in 2 sec. Find (i) the acceleration (ii) distance travelled by car assume motion of car is uniform?

An aircraft executes a horizontal loop of radius 1.00 km with a steady speed of 900 km/h. Compare its centripetal acceleration with the acceleration due to gravity

A car and a bus start from a place P at the same time and move non-stop towards a place where the distance between P and Q is 210 km. The car takes half an hour less than the bus to arrive Q. If the average speed of the car is 10 km/h more than that of the bus, find the average speed of the car and the bus.

A car is travelling at a speed of 90 km/h. Brakes are applied so as to produce a uniform acceleration of – 0.5 m/s2. Find how far the car will go before it is brought to rest?

A car is moving at a velocity 72 km/h. Brakes were applied. After moving a distance 200 m the car attains velocity 36 km/h. Find (i) acceleration of the car

Abdul, while driving to school, computes the average speed for his trip to be 20 km h-1 . On his return trip along the same route, there is less traffic and the average speed is 30 km h^-1 . What is the average speed for Abdul's trip?

A car moving along a straight highway with a speed of 126 km h^-1 is brought to a stop within a distance of 200 m. What is the retardation of the car (assumed uniform), and how long does it take for the car to stop?
