Answer:
West
Explanation:
This is because the first caar has more mass
Answer:
3924 N
5124 N
4004 N
2884 N
4004 N
Explanation:
m = Mass of elevator = 400 kg
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration
f = Friction force = 80 N
When the elevator is stationary only the acceleration due to gravity will be acting on it
Tension
The tension is 3924 N
The balanced force equation would be
The tension is 5124 N
When velocity is constant acceleration is zero
The tension is 4004 N
The tension would be 2884 N
When velocity is constant acceleration is zero
The tension is 4004 N

Answer:
Force = 485000 Newton.
Explanation:
Given the following data;
Mass = 485000 kg
Initial velocity = 20m/s
Final velocity = 25m/s
Time, t = 5 seconds
To find the force;
First of all, we would calculate the acceleration of the train i.e the rate of change of the velocity of the train with respect to time.
Mathematically, acceleration is given by the equation;
Where;
a is acceleration measured in
v and u is final and initial velocity respectively, measured in
t is time measured in seconds.
Substituting into the equation, we have;
Acceleration = (25 - 20)/5
Acceleration = 5/5
Acceleration = 1m/s²
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Force = mass * acceleration
Force = 485000 * 1
Force = 485000 Newton.
