Answer:
s = 0.9689 m
Explanation:
given,
Height of fall of paratroopers = 362 m
speed of impact = 52 m/s
mass of paratrooper = 86 Kg
From from snow on him = 1.2 ✕ 10⁵ N
now using formula
F = m a
a = F/m
Using equation of motion
v² = u² + 2 a s
s = 0.9689 m
The minimum depth of snow that would have stooped him is s = 0.9689 m
Explanation:
You would think it should. But remember the Force is also determined by mass. The mass of the earth markes our mass like the smallest part of a mosquito leg. The earth will go on it its merry way without cosidering us at all.
Gravitational Potential Energy (GPE) = 9.8m/s² (rate of gravity) x 8,000,000kg of water x 50.0m
GPE = 3,294,000,000 Joules (J) which is also the change in GPE
Explanation:
An object's weight depends on the pull of the gravitating object but the object'<u>s mass is independent of the gravity. </u>
Answer:
Explanation:
When a force is applied to an object over a certain period of time, it is said to apply an impulse to the object. The magnitude of the impulse is given by:
J=F*Δt
When an impulse is provided to an object, the momentum of the object will change, as in:
J=Δp=
So given:
Initial momentum
Applied force
J=
F*Δt=
