The distance is 60 + 45 = 105km
The displacement is 60 - 45 = 15km
The distance is the total the car drove .
The displacement is the distance between starting point and ending point .
Answer:
56 m/s
Explanation:
The time we are considering is
t = 15 s
The vertical velocity of the projectile is given by

where
is the initial vertical velocity
is the acceleration due to gravity
Substituting t=15 s, we find the vertical velocity of the projectile at that time:

where the negative sign means the direction is now downward.
The horizontal velocity does not change since there are no forces acting along that direction, so it remains constant:

So, the magnitude of the velocity at the moment of impact is

It's revolution, and no, that would be a rotation.
The answer is B
The gravitational force exerted from the planet on Moon is eight times larger than the gravitational force exerted from the planet on Moon .
