1. The problem statement, all variables and given/known data Marian, who is standing on her balcony, is surprised by a pigeon and throws a flowerpot up in the air at 2.1 m/s. It takes 3.0 s for the flowerpot to smash to the ground. The flowerpot experiences acceleration due to gravity of 9.81 m/s2 [down]. Determine how high Marian's balcony is and how fast the flowerpot was moving just before it smashed to the ground. 2. Relevant equations d= v1 Δt+ ½ a Δt2 v22= v12 + 2 aΔd 3. The attempt at a solution Given: V1 = 2.1 m/s (up) a = 9.81 m/s2 (down) t= 3.0 s Determine how high Marians balcony is: Δd= v1 Δ t+ ½ a Δt2 d= (2.1 m/s) (3.0s) - ½ (9.81 m/s2) (3.0s)2 = -37.8 m Δd = 38 m Marian’s balcony is 38 m high. Calculate how fast the flowerpot was moving before it smashed to the ground: v22 = v12 + 2 aΔd v22 = (2.1 m/s)2 + 2 (9.81 m/s2) (38 m) v22 = √750 v22= 27 m/s (down) The flowerpot was travelling 27 m/s (down) before it smashed to the ground. Is this correct?
