Tidal bulges are always on the opposite side of the Earth.
They are created because of the gravitational influence of the Moon on Earth and inertial's counter balance.
The side of the Earth that is facing the Moon is the closest to the Moon, and the gravitational force is the strongest when the distance is the smallest.
As the Moon is trying to draw the water towards itself, the inertia tries to keep the water at its place. On the opposite side of the Earth, "behind the Moon", the gravitational force of the Moon is the weakest, so inertia is the strongest. That's why tidal bulges are at the opposite side.
F = force applied to stop the car = - 3000 N
m = mass of the car = 3000 kg
a = acceleration of the car = ?
v₀ = initial velocity of the car before the force is applied to stop it = 10 m/s
v = final velocity of the car when it comes to stop = 0 m/s
d = stopping distance of the car
acceleration of the car is given as
a = F/m
inserting the values
a = - 3000/3000
a = - 1 m/s²
using the kinematics equation
v² = v²₀ + 2 a d
inserting the values
0² = 10² + 2 (-1) d
0 = 100 - 2 d
2 d = 100
d = 100/2
d = 50 m
hence the correct choice is
C. 50 m

Answer:
-14 kg m/s
Explanation:
Taking the direction "to the left" as positive direction, the initial momentum of the ball is
p1 = +8 kg m/s
while the final momentum is
p2 = -6 kg m/s
so the change in momentum is

According to the impulse theorem, the impulse exerted on the ball is equal to the change in momentum of the ball, so:
(which means 14 kg m/s to the right)
While the impulse that the ball exerted on the ball is equal and opposite in direction, so:
(which means towards the left)
