Answer:
Rh = 97.67 m
Explanation:
given data
mass = 2400 kg
lands = 293 mm
solution
as here boulder is thrown upward so at some point will be hightest so at that velocity will be zero
so we apply here conservation of momentum
0 = m1 × v1 - mh × vh ...............1
m1 × v1 = mh × vh
× 2400 × v1 = × 2400 × vh
v1 = 3 vh
and
R = speed × time
time =
and
Rh = vh × time
Rh = v1 ×
Rh = 97.67 m
According to my guesses, he should have swung the pendulam bob and noted its time period. In order to observe the effect of mass, he would have repeated the experiment with varied pendulam bobs. Hope this helped!
Answer:
There is no gravity in outer space so how will any object fall in the first place
Also the principle of terminal velocity is limited to free fall where the acceleration is equal to the gravity of the planet
Liquid water freezes and becomes solid ice when the molecules lose energy
Answer:
D because those are both concerning.
