Answer: 1
Explanation:
Given
Tension is the string
mass of object
Tension is greater than the weight of the object i.e. elevator is moving upward
we can write
A spring is compressed between two objects with unequal masses, m and M, ad held together. The objects are initially at rest on

The second ball traveled a greater distance when compared to the first ball because the second ball spent more time in motion.
The given parameters;
- time of fall of the first ball, t = 1 s
- time of fall of the second ball, t = 3 s
The distance traveled by each ball is calculated using the second equation of motion as shown below.
The distance traveled by the first ball is calculated as follows;
The distance traveled by the second ball is calculated as follows;
Thus, the second ball traveled a greater distance because it spent more time in motion.

Answer:
0.2 m/s^2
Explanation:
Maximum distance, h = 19.5 m
initial speed, u = 2.80 m/s
final speed, v = 0 m/s
Let the gravitational acceleration is a.
Use third equation of motion
a = 0.2 m/s^2
Thus the gravitational acceleration on the exoplanet is 0.2 m/s^2
