a body moves on frictionless surface forward along a straight line it uses q velocity 48km/hr for ⅓ of the total path and it's motion is continued so that it uses 52 km/hr for ⅔ of the total path then calculate the average velocity of the body

28. a stone is projected at a cliff of height h with an initial speed of 42.0 mls directed at angle θ0 = 60.0° above the horizontal. the stone strikes at a, 5.50 s after launching. find (a) the height h of the cliff, (b) the speed of the stone just before impact at a, and (c) the maximum height h reached above the grou
