On a windless day a cyclist goes an incline uphill at a constant speedof 12 km/hr and downhill on same incline at 16 km/hr. Air resistance isproportional to square of his speed and his maximal effort which heapplies on pedal which causes friction on tyre to move the cycle isindependent of speed. His maximum speed on his maximal effort on aflat road is close to :-(A) 20 km/hr(C) 22 km/hr(B) 18 km/hr(D) 14 km/hr

The speed of the cyclist going uphill vu = 12 km/hr The speed of the cyclist going downhill vd = 16…

Imagine the cart was dropped from rest from a height of 2.5m and allowed to free fall (assume air resistance is negligible). Compare the final speed achieved using (a) conservation of energy and (b) force and motion equations.
A skier starts at the top of a frictionless slope and pushes off with a speed of 3.0 m/s. The elevation of the slope is 40 m. She skis down the slope to a valley with elevation 0.0 m and then glides to the peak of an adjacent slope that is at an elevation of 25 m. Calculate her speed at the second peak
The speed of a crate traveling on a horizontal frictional surface changes from vi=13 m/s to vf=11.5 m/s in a distance of d=8.5 m.

(B) if the crate has a mass of 1kg, what is the power supplied to the crate by friction? (C) what is the coefficient of kinetic friction between the crate and the surface uk?
A 1000-kg automobile accelerates up a hill, increasing its speed from 5 mi/h to 50 mi/h, along a straight 100-m stretch of road. If the hill makes an angle of 5° with respect to the horizontal, find the total work done by the automobile.
A box with a mass 2.0 kg that initially slides on the floor with a speed of 5.0 m/s is accelerated at a ratio of 4.0 m/s^2 times 10.0s. Find the net work done on the box.
Neglecting friction and air resistance, a car with an initial velocity of 43.1 km/h coasts up a hill and comes to stop at the hill's top. What must be the height of the hill (in meters)? Hint: you do not need the car's mass to solve this problem, but if interested to solve the problem using kinetic and potential energies you can use a mass of 2000kg for the car.
