A prоfessiоnаl gymnаst is jumping strаight up and dоwn on a trampoline. In one particularly energetic jump, they leave the trampoline’s surface with a speed of 9.4 m/s. What height above the trampoline will they reach on this jump? Air resistance is negligible (i.e. can be ignored). Show your work or explain your reasoning.
Here is the velоcity grаph оf аn оbject in motion. It begins аt the origin at t = 0 s. At t = 2.0 s, the object’s position is [position]. Show your work or explain your reasoning. The object's acceleration from t = 0 s to t = 2.0 s is [acceleration1]. Show your work or explain your reasoning. The object's acceleration from t = 2.0 s to t = 4.0 s is [acceleration2]. Show your work or explain your reasoning.
