If a projectile is shot at an angle of #pi/3# and at a velocity of #29 m/s#, when will it reach its maximum height?? Physics 1D Motion Falling Objects 1 Answer ali ergin May 2, 2016 #t=2,56 " "s# Explanation: #alpha=pi/3" sin (pi/3)=0,866# #"initial velocity :"v_i=29 " "m/s# #"it has "v_y=0"; if object reaches its maximum height."# #v_y=v_i*sin alpha-g*t# #0=v_i*sin alpha-g*t# #t=(v_i*sin alpha)/g" elapsed time to the maximum height"# #t=(29*0,866)/(9,81)# #t=2,56 " "s# Answer link Related questions Question #50365 Question #d6555 What is the definition of free fall?
