Question

10)
Aisha dropped an object of mass 4 Kg from a height of 10m.
The object has a speed of 0 m/s at position A and is at a height
of 10m above the ground. At position B, the object is om above
the ground. At position C, the object is 4m above the ground.
At point D, the object is mere picometer (almost at 0 meter height)
above the ground. Assume negligible air resistance throughout
the motion. Use this information to fill in the table. (g=10m/s2​

Answer 1

Answer:

H Ep Ek V Ep+Ek

A 10 400 0 0 400

B 6 240 160 4√5 400

C 4 160 240 2√30 400

D 0 0 400 10√2 400

we simply use Ep=mgh Ek= 1/2mv² and

v²=2mgh
