So, the time that taken for the astronaut to fall to the surface of the moon is <u>2.5 s.</u>
<h3>Introduction</h3>
Hi ! In this question, I will help you. In this question, you will learn about the fall time of the free fall motion. Free fall is a downward vertical motion without being preceded by an initial velocity. When moving in free fall, the time required can be calculated by the following equation:



With the following condition :
- t = interval of the time (s)
- h = height or any other displacement at vertical line (m)
- g = acceleration of the gravity (m/s²)
<h3>Problem Solving</h3>
We know that :
- h = height = 5.00 m
- g = acceleration of the gravity = 1.6 m/s²
What was asked :
- t = interval of the time = ... s
Step by step :




<h3>Conclusion</h3>
So, the time that taken for the astronaut to fall to the surface of the moon is 2.5 s.

m1v1 + m2v2 = m1V1 +m2V2
v: velocity before collision, V after collision
<span>the magnitude of the final velocity of the red marble
</span>m1v1 + m2v2 = m1V1 +m2V2
V2 is the final velocity we must find
V2 = 1 / m2 ( m1v1 + m2v2 - m1V1)
= 1/1.2 (3.5x15 + 1.2x 3.5 - 3.5x 5.5)= 63.29 cm/s

Answer:
4.3 * 10 N
Explanation:
To calculate torque, we multiply the distance from the pivot by the perpendicular (the part of the force that acts at right angles to the displacement vector) component of the force to the displacement vector from the pivot.
torque = distance from pivot * perpendicular force
170 Nm= 0.4 m * F
F = 425 N = 4.3 * 10 N rounded off to two significant figures
