The value of `u` so that the ball reaches at point A (g = 10`m//s^(2)`)

Track OABCD (as shown in figure ) is smooth. What minimum speed has to be given to a particle lying at point A, so that it can reach point C? (take g=10 m//s^2 )

A ball is thrown from the top of a 60m high tower with velocity 20sqrt(2)m//s at 45^(@) elevation.Find the radius of curvature of path at highest point. ( g=10m//s^(2) )

A ball is dropped onto a step at a point P and rebounds with velocity u_@ at an angle of 45^@ with the vertical. The value of u_0 knowing that just before the ball hits the point Q its velocity forms an angle 30^@ with the vertical is: (g=10m//s^2)

A boy throws a ball upward with velocity v_(0)=20m//s . The wind imparts a horizontal acceleration of 4m//s^(2) to the left. The angle theta at which the ball must be thrown so that the ball returns to the boy's hand is : (g=10ms^(-2))

A boy throws a ball upward with velocity v_(0)=20m//s . The wind imparts a horizontal acceleration of 4m//s^(2) to the left. The angle theta at which the ball must be thrown so that the ball returns to the boy's hand is : (g=10ms^(-2))

A ball is thrown upward at an angle of 45^(@) with the horizontal and lands on the top edge of a builing that is 20 m away. The top edge is 10 m above the throwing point. The initial speed of the ball in metre/second is (take g = 10 m//s^(2))

A football player throws a ball with a velocity of 50 m//s at an angle 30 degrees from the horizontal. The ball remains in the air for (g = 10m//s^(2))

A ball is dropped from a height of 10 m. If the energy of the ball reduces by 40% after striking the ground, how much high can the ball bounce back ? (g = 10m//s^2)

A ball is thrown with a velocity whose horizontal component is 12 ms^-1 from a point 15 m above the ground and 6 m away from a verticlewall 18.75 m high in such a way so as just to clear the wall. At what time will it reach the ground ? (g = 10 ms^-2) .

A ball is projected vertically up wards with a velocity of 100 m/s. Find the speed of the ball at half the maximum height. (g=10 m//s^(2))
