Could someone check these for me? i was told to put g = 9.8 m/s for all calculus questions, and I think it's a bit ridiculous.
1. A long jumper running at 8 m/s jumps into the air, rising to a height of 0.7 metres. What is the length of the jump.
This is wrong. the answer says 5.29 m.
2. The velocity of a point moving along the x axis is given by
Show that it is simple harmonic.
However this is not the form
so how would I do this?
Thanks!!! You guys are really helpful!
