A truck can move up a road which has a gradient of 1 m rise every 50 m with a speed of 24 kmph ? How fast will the same truck move down the hill with the same horse power ? The air resistance to the motion of the truck is 1/25 of its weight.

A truck can move up a road having a grade of 1.0 m rise for every 50 m with a speed of 18(km)//(h) . The resisting force is equal to (1)//(25) of the weight of the truck. With what speed the same truck moves down the hill with the same power?

A truck moves up a hill of icline 1 in 50 with a speed of 20 KMPH. If the resistance to the motion of the truck is 4% its weight, the speed of te truck while moving down hill utilising the same power is

A truck of mass 30,000 kg moves up an inclined plane of slope 1 in 100 at a speed of 30 kmph . The power of the truck is (g=10ms^(-1))

A car can pull a trailer of twice its mass up a certain slope at a maximum speed v=1m//s . Without the trailer the maximum speed of the car up the same slope is 2v . The resistance to the motion is proportinal to mass and square of speed. If the car (without trailer) starts to move down the same slope, with its engine shut off, eventually it will acquire a constant speed v_(t) , then find v_(t)^(2) (in m^(2)//s^(2) )

A car and a truck are moving with the same speed of 12ms^(-1) . If their masses are in the ratio 1:5 , find the ratio of their kinetic energy.

A car weighing 550 kg, ascends a hill with a gradient of 1 in 6 at a speed of 36 kmph. Find how much work is done per second, (a) in moving the car up the hill overcoming a total force of friction and air resistance equal to 350 kgwt.
