okay so this is kinnda new to me...
umm okay lets get started...
what is potentail energy of a 500kg dolphin if it is 3m up in i the air...
1.4) if this was the maxium height of its jump, how much moving energy would the dolphin have just before it hits the water???
A 60kg object rest on top of an 80m high cliff. If it falls off, and we ignore air resistance,calculate:
2.2) the fastest speed that it reaches...
2.3)its mechanical energy after 2.7 s
2.4)Ep+Ek when it is 17.4m above the ground
2.5)its speed when it is 35 m above the ground...
