velocity of v(0)=50 m/s satisfies the rela- tionship y(t) = v(0)1 - grm. where g = 9.81 m/s is the acceleration due to gravity. 3(1) Figure P8.3 A projectile in the vertical plane. Find the following: (a) Write the quadratic equation for the height y(t) of the ball. (b) The velocity v(t) = dy(1) (c) The acceleration a(t)= (d) The time required to reach the max- imum height, as well as the cor- responding height ymar Use your results to sketch y(r). 8-3.
