A standard car developes 40 H.P. Find the maximum speed the car can attain agains a resistance of 20kg wt. due to air and friction. Gvien efficiency of the engin is `25%.1H.P.=746W ` and `g=10ms^(-2)`.

Find the maximum speed at which a car can take turn round a curve of 30 cm radius on a level road if the coefficient of friction between the tyres and the road is 0.4. Take g = 10 ms^(-2) .

Find the maximum speed at which a car can turn round a curve of 30 m radius on a level road if coefficient of friction between the tyress and road is 0.4. Take g = 10 m//s^(2) .

Find the power of an engine which can maintain speed of 50ms^(-1) for a train of mass 3xx10^(5) kg on a rough line. The coefficient of friction is 0.05 . Take g=10ms^(-2)

A box of mass 2 kg is placed on the roof of a car. The box would remain stationary until the car attains a maximum acceleration. Coefficient of static friction between the box and the roof of the car is 0.2 and 1 g=10" ms"^(-2) . The maximum acceleration of the car, for the box to remain stationary, is

What is the maximum speed at which a car can turn round a curve of 30 m radius on a level road if the coefficient of friction between the types and the road is 0.4 .(Given, acceleration due to gravity = 10 ms ^(-2)

A truck of amss 10 ton is movng up an incline of 1 in 50 with a uniform velocity of 72 km/h. If the resistance opposing the motion of the truck due to friction is 5 kg per ton, the power of the engine is (g=10m//s^(2))

If the crest of the hill has a radius of curvature p determine the maximum constnat speed at which the car can travel over it without leaving the surface of the road. Neglect the size of the car in the calculation. The car has mass m. Given p=40m, m=1700kg, g=10m//s^(2)

The maximum speed (in ms^(-1) ) with which a car driver can traverse on a horizontal unbanked curve of radius 80 m with coefficient of friction 0.5 without skidding is : (g = 10 m/ s^(2) )
