Answer:
Explanation:
Given that,
Initially, the spaceship was at rest, u = 0
Final velocity of the spaceship, v = 11 m/s
Distance accelerated by the spaceship, d = 213 m
We need to find the acceleration experienced by the occupants of the spaceship during the launch. It is a concept based on the equation of kinematics. Using the third equation of motion to find acceleration.
So, the acceleration experienced by the occupants of the spaceship is .
Answer:
a)
b)
Explanation:
From the question we are told that:
1st segment
243km at Angle=30
2nd segment
178km West
Resolving to the X axis
Resolving to the Y axis
Therefore
Generally the equation for Directional Angle is mathematically given by
Generally the equation for Magnitude is mathematically given by
The time taken for Train A to be 39.1 miles ahead of Train B is 2.7 hours
<h3>How to determine the relative speed</h3>
- Speed of Train A = 41.1 mph
- Speed of Train B = 26.5 mph
- Relative speed =?
Relative speed = 41.1 - 26.5
Relative speed = 14.6 mph
<h3>How to determine the time to be 39.1 miles apart</h3>
- Relative speed = 14.6 mph
- Distance = 39.1 miles
- Time =?
Relative speed = distance / time
14.6 = 39.1 / time
Cross multiply
14.6 × time = 39.1
Divide both side by 14.6
Time = 39.1 / 14.6
Time = 2.7 hours
Thus, it will take train A 2.7 hours to be 39.1 miles ahead of Train B
