If a projectile is shot at an angle of #pi/4# and at a velocity of #24 m/s#, when will it reach its maximum height?? Physics 1D Motion Falling Objects 1 Answer ali ergin Jun 4, 2016 #t=1.73" "s# Explanation: #"you can calculate using the formula t="(v_i*sin alpha)/g# #alpha=pi/4" ; "sin(pi/4)=0.707" ; "v_i=24" "m/s# #t=(24*0.707)/(9.81)# #t=1.73" "s# Answer link Related questions Question #50365 Question #d6555 What is the definition of free fall?
