Answer:
Explanation:
a) diagram is shown in attached figure.
b)
Resultant Force= Fnet= 2000-1000= 1000 N (upward)
c)the force will lift parachutist upward with acceleration =Fnet/ m
where m is mass of parachutist
m=weight/g
=1000/10=100 kg
acceleration of parachutist=Fnet/ m
=1000/100
a=10 m/s²
Answer:
In the explanation
Explanation:
<u>Experiment</u>:
Consider two billiard balls of masses ‘m₁’ and ‘m₂’, moving with velocities ‘u₁’ and ‘u₂’, respectively, such that u₁ is greater than u₂. After some time, these balls collide with each other and their velocities become ‘v₁’ and ‘v₂’, respectively.
<u>Observation</u>:
The masses of balls should be measured and their initial and final velocities should be measured.
<u>Result</u>:
In order to prove law of conservation of moment following equation must be satisfied by observed values:
