Answer:
The force of gravity after you double the mass and the distance is half of the initial force:
Explanation:
The initial force of gravity is:
where is the universal gravitational constant,
is the mass of the first object,
is the mass of the second object, and
is the distance between the objects.
If the mass of the second object is doubled, now we have , and if the distance between the objects is also doubled instead of
now we have
.
So the force of gravity now is:
and we know that
so the new force of gravity is:
The force of gravity after you double the mass and the distance is half of the initial force.
Answer:
Explanation:
Given
Initial Velocity (u)=13 m/s
angle
distance between fence and deer=2.5 m
We consider deer jump similar to projectile motion
equation of trajectory
Thus deer will cross the fence with an difference in its jump and fence
1.5-1.148=0.351 m
so deer rises during when it is over fence
