A roller coaster car has mass of 1300 kg when fully loaded with passengers. As the car passes over the top of a circular hil of radius 20m, its speed is not changing. At the top of the hill, what are the (a) magnitude F_(N) and (b) direction (up or down) of the normal force on the car from the track if the car's speed is v=11m/s? What are (C) F_(N) and (d) the direction if v=14m/s?

Two , guns situated on the top of a hill of height 10 m , fire one shot each with the same speed 5 sqrt( 3) m s^(-1) at some interval of time . One gun fires horizontally and other fires upwards at an angle of 60(@) with the horizontal . The shots collide in air at a point P . Find (i) the time - interval between the firings , and (ii) the coordinates of the point P . Take origin of the coordinates system at the foot of the hill right below the muzzle and trajectories in x-y plane .

    A train with a length of L=1050m moves uniformly on the horizontal section of rail road.However the train encounters a small hill that slopes gently.With what minimum speed v (in m/s ) can the train cross the hill? The base of hill has a length l=100m the lengths of the slope are l_(1)=80m and l_(2)=60m .The slope of hills can be consider as straight lines and the small section of rounding at the top of the hill can be ignored.Neglect air drag.(take g=10m/s^(2) ).

    A particle is thrown horizontally from the top of a tall tower with a speed of 10m/s. if radius of curvature of path followed is 4sqrt(2k m at t=1sec, then find the value of k.

    Largely because of riding in cars, you are used to horizontal circular motion. Vertical circular motion would be a novelty. In this sample problem, such motion seems to defy the gravitational force. In a 1901 circus performance, Allo Dare Devil Diavolo introduced the stunt of riding a bicycle in a loop the loop. Assuming that the loop is a circle with radius R=2.7m, what is the least speed v that Diavolo and hisbicycle could have at the top of the loop to remain in contact with it there?

    Two guns situated at the top of a hill of height 10 m fire one shot each with the same speed 5sqrt(3) m//s at some interval of time. One gun fires horizontal and the other fores upwards at an angle of 60^(@) with the horizontal. Two shots collide in air at a poit P . Find (i) time-interval between the firing and (ii) coordinates of the point P . Take the origin of coordinates system at the foot of the hill right below the muzzle and trajectorise in the x-y plane.

    In fig a stuntman drives a car (without negative lift) over the top of a hill, the cross section of a hill, the cross section of which can be approximated by a circle of radius R=250 m. What is the greatest speed at which he can drive without the car leaving the road at the top of the hill?
