A particle projected with velcoity `v_(0)` strikes at right `alpha` plane through the point of projection .

A particle is projected vertically upward with velocity u from a point A , when it returns to the point of projection .

A ball is projected obliquely with a velocity 49 ms^(-1) strikes the ground at a distance of 245 m from the point of projection. It remained in air for

A particle of mass 'm' is projected with velocity v_(0) at an angle 'alpha' with the horizontal. The coefficient of restitution for any of its impact with the smooth ground is e . Find total time taken by the particle before it stops moving vertically?

A particle is projected with a certain velocity at an angle alpha above the horizontal from the foot of an inclined plane of inclination 30^(@) . If the particle strikes the plane normally then alpha is equal to

A particle is projected with a velocity 10 m//s at an angle 37^(@) to the horizontal. Find the location at which the particle is at a height 1 m from point of projection.

A particle is projected with a velocity bar(v) = ahat(i) + bhat(j) . Find the radius of curvature of the trajectory of the particle at (i) point of projection (ii) highest point .

A particle is projected with velocity v at an angle theta aith horizontal. The average angle velocity of the particle from the point of projection to impact equals

A ball is projected from a point in a horizontal plane so as to strike a vertical wall at right angle A .after rebounding from the wall it strikes the horizontal plane once and returns to the point of projection just before second collision at horizontal surface. Find co-efficient of restitution for the two collisions, assuming it to be same for both the collision.

An object is projected horizontally from a top of the tower of height h. The line joining the point of projection and point of striking on the ground makes an angle 45^@ with ground, then with what velocity the object strikes the ground

Particle A is relased form a point P on a smooth inclined plane inclined at an angle alpha with the horizontal. At the same instant another particle B is projected with initial velocity u making an angle beta with the horizontal .Both particle again on inclined plane. What is relation between alpha and beta .
