A particle is thrown with speed u at an angle of projection θ with horizontal as shown. (i) The average velocity of particle from O to A is ucosθ (ii) The average velocity of particle from O to H (highest point) is u/21+3cos2θ−−−−−−−−−√ (iii) The average velocity of particle from J to K is u cos θ (iv) The angle between the velocity and the acceleration between O and H is greater than 90^∘, between H to A is less than 90^∘ and at highest point is 90^∘
