Solutions: a. v after is use: V₁ = V₁ - gt vy=20 m/s-(9.8 m/s²)(1.0s) vf= 20 m/s -9.8 m/s vf = 10.2 m/s b. v after 2s use: c. d after 1s use: v₁ = v₁ - gt vy=20 m/s-(9.8 m/s²)(2.0s) vf= 20 m/s - 19.6 m/s vf = 0.4 m/s d = v₁t - 912 2 d=20m/s(1.0s) - (9.8 m/s²)(1.0s)² 2 d=20m-4.9 m d=15.1 m (positive sign denotes that the object is moving upward) d. t from origin to maximum height Note: An object thrown upward will reach a certain point (maximum height) where it will momentarily stop and then start to move downward. At this point, vy= 0. V₁ = V₁ - gt Use: Manipulating the equation, V₁ - Vf 9 t = t=20 m/s-0 9.8 m/s² t = 2.04 s e. d from origin to maximum height use: d = v₁t d=20m/s (2.04 s) - (9.8 m/s²)(2.04s)² - gt² 2 2 d = 40.8 m -20.40 m d = 20.4 m
