A body is moving in a circle with a speed of 1ms^−1. This speed increases at a constant rate of 2ms^−1 every second. Assume that the radius of the circle described is 25 m. The total acceleration of the body after 2s is:

A particle is projected with certain velocity at an angle α above the horizontal from the foot of an inclined plane of inclination 30 . If the particle strikes the plane normally then α is equal to
