If a projectile is shot at an angle of #(pi)/8# and at a velocity of #17 m/s#, when will it reach its maximum height? Physics 1D Motion Falling Objects 1 Answer ali ergin Feb 10, 2016 #t_m=0,6632 s# #h_m=2,1564 m# Explanation: #alpha=pi/8*180/pi=22,5^o# #t_m=v_i*sin alpha/g# #t_m=17*sin (22,5)/(9,81)# #t_m=0,6632 s" elapsed time to reach maximum height"# #h_m=(v_i^2*sin^2 alpha)/(2*g)# #h_m=(289*0,1464)/(19,62)# #h_m=2,1564 m " maximum height"# Answer link Related questions Question #50365 Question #d6555 What is the definition of free fall?
