At time t = 0, Object 1 is thrown straight upward with initial speed 30 m/s from the edge of a tall cliff.
Object 1 hits the ground with an impact speed of v1 m/s at time t = t1 s.
At time t = 0, Object 2 is thrown straight downward with initial speed 30 m/s from the edge of the same cliff.
Object 2 hits the ground with an impact speed of v2 m/s at time t = t2 s.
Which one of the following is true?
At time t = 0, Object 1 is thrown straight upward with initial speed 30 m/s from the edge of a tall cliff. Object 1 hits the ground with an impact speed of v, m/s at time t = 11 s. At time t = 0, Object 2 is thrown straight downward with initial speed 30 m/s from the edge of the same cliff. Object 2 hits the ground with an impact speed of v2 m/s at time 1 = 12 S. Which one of the following is true? vi > V2 and 11 <12 <V2 and 11 =12 Vi < V2 and 11 <12 Ov> V2 and 1>12 OV > V2 and 11 = 12 vi = V2 and 11 <12 V = V2 and 11 = 12 OV <12 and 1>12 v=v2 and 1>t2
