Answer: Yes.
Explanation:
Assuming Earth and Moon are isolated is space, it is possible to have a point where Earth and Moon will pull at an object with equal force.
That point will be closer to the Moon than the Earth because Moon's gravitational field strength is weaker than Earth's gravitational field strength.
Explanation:What is centripetal acceleration?
Can an object accelerate if it's moving with constant speed? Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object—even if the object is maintaining a constant speed—still count as acceleration.
Acceleration is a change in velocity, either in its magnitude—i.e., speed—or in its direction, or both. In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant. You experience this acceleration yourself when you turn a corner in your car—if you hold the wheel steady during a turn and move at constant speed, you are in uniform circular motion. What you notice is a sideways acceleration because you and the car are changing direction. The sharper the curve and the greater your speed, the more noticeable this acceleration will become. In this section we'll examine the direction and magnitude of that acceleration.
The figure below shows an object moving in a circular path at constant speed. The direction of the instantaneous velocity is shown at two points along the path. Acceleration is in the direction of the change in velocity, which points directly toward the center of rotation—the center of the circular path. This direction is shown with the vector diagram in the figure. We call the acceleration of an object moving in uniform circular motion—resulting from a net external force—the centripetal acceleration

Answer:
total time = 65 seconds
total distance = 1554 meters
Explanation:
kinematic equation:
final velocity = initial velocity + acceleration multiplied by time
v_1 = v_0 + at
28 m/s = 0 m/s + 2 m/s^2 (t)
t = 14 seconds
a) total time = 14 + 46 + 5 = 65 seconds
b) must solve for total distance and divide it by time.
d_1 = v_0t + 1/2 a * t^2
d_1 = 0 + 0.5(2) * 14^2
d_1 = 196 meters
d2 = vt
d2 = 28 *46
d2 = 1288 meters
v_1 = v_o + at
0 = 28 + a(5)
- 28/5 = a
a = - 5.6 m/s^2
d_3 = v_0t + 1/2 a * t^2
d_3 = 28 (5) - 0.5(5.6)*5^2
d_3 = 70 meters
total distance = d1 + d2 + d3 = 196 + 1288 + 70 = 1554 meters
