Question #98a41 Physics 1D Motion Displacement and Velocity 1 Answer P dilip_k Oct 7, 2016 Let #u-> "Initial velocity of the ball"=2.2" m/s"# #v-> "Final velocity of the ball"=0" m/s"# #s-> "Length of ascent along the slope"=3.2m# #t-> "Time of ascent along the slope"# Since the motion occurs with constant retardation,we can write #1/2(u+v)xxt=s# #=>1/2(2.2+0)xxt=3.2# #=>t=3.2/1.1~~2.9s# Answer link Related questions What is the difference between distance and displacement?
