Time taken by a car is inversely proportional to the speed of the car

A power output from a certain experimental car design to be shaped like a cube is proportional to the mass m of the car. The force of air friction on the car is proportional to Av^(2) , where v is the speed of the car and A is the cross-sectional area. On a level surface the car has a maximum speed v_("max") . Assume that all versions of this design have the same density. The v_("max") is propotional to m^(1//c) . Find C

Assume the aerodynamic drag force on a car is proportional to its speed. If the power output from the engine is doubled, then the maximum speed of the car

A car covers 300 km in 15 h. Find the speed of the car.

The increase in the speed of a car is proportional to the additional petrol put into the engine. Is it possible to accelerate a car without putting more petrol or less petrol into the engine?

Speedometer measures the speed of the car in

A car drive accelerates the car to increase its speed from 30 km h^(-1) to 60 km h^(-1) in 5 min. Arrage the following steps a sequence to obtain the acceleration of the car. (A) Use the formula , rate of change of velocity = (" Total change in veclocity")/("Total time required for change") (B) Obtain the final velocity (v) , of the car. (C) Find the time taken to increase the speed of the car from u to v let it be 't' (D) find the initial velocity (u) of the car. (E) Substitute the values in the formula and calulate the acceleration of the car.

A car travels from Delhi to Jaipur at a speed of 50 km/hr and another car travels from Delhi to Ludhiana at a speed 60 km/hr. If the time taken by both the cars is the same and the distance of Jaipur from Delhi is 270 kms, then find the distance of Ludhiana from Delhi.
