Compute all parts of given question:
Question: An impala is an African antelope capable of a remarkable vertical leap. In one recorded leap, a 45 kg impala went into a deep crouch, pushed straight up for 0.21 s, and reached a height of 2.5 m above the ground.
Part I: To achieve this vertical leap, with what force did the impala push down on the ground?
Part II: What is the ratio of this force to the antelope's weight?
I need help to find with what force the impala pushed down on the ground.
The Pierre Auger Observatory site mentions the detection of a 3E20 eV (48 J) cosmic ray whose energy, well above the GZK cut off, was based on an analysis of its atmospheric shower. This was equivalent to the kinetic energy of a baseball by a speed o..
