7(a) Find the radial and transverse components of the velocity of a particle moving along the curve ax2 +by2 =1 at any time t if the polar angle = ct2. 9 (b) A particle is projected vertically upwards. After a time t, another particle is sent up from the same point with the same velocity and meets the first at height h during the downward flight of the first. Find the velocity of projection. 8 7(a) Find the radial and transverse components of the velocity of a particle moving along the curve ax2 +by2 =1 at any time t if the polar angle = ct2. 9 (b) A particle is projected vertically upwards.
