Question

A high jumper leaps into the air with an initial speed of 5.8 m/s.How high will she be at the top of her flight when v=0?

An airplane traveling horizontally at 78 m/s at an elevation of210m drops bales of hay to cows stranded in a snowstorm. At whathorizontal distance from the cows should the bales be dropped.Ignore air resistance. Calculate the velocity of a bale as itreaches the ground?

A car accelerates from rest at 2.3 m/s^2. Calculate its speed after10s and the distance it travels in that time?

Explanation / Answer

given intial speed of high jumper = u = 5.8m/s when v = 0 she reaches maxium height    Hmax = u2/2g             = (5.8)2/2*9.8 = -------m
