If a projectile is shot at an angle of #(pi)/8# and at a velocity of #32 m/s#, when will it reach its maximum height? Physics 1D Motion Falling Objects 1 Answer ali ergin May 10, 2016 #t=1.24 "sec"# Explanation: #"the vertical component of velocity is zero,if Object reaches its maximum height"# #v_y=v_i*sin alpha-g*t# #0=32*sin(pi/8)-9.81*t# #0=32*0.38-9.81*t# #0=12.16-9.81*t# #9.81*t=12.16# #t=(12.16)/(9.81)# #t=1.24 "sec"# Answer link Related questions Question #50365 Question #d6555 What is the definition of free fall?
