Answer:
Velocity will be 2.886 m/sec
Explanation:
We have given arm length = 0.70 m
And distance from the handle to surface = 15 cm =0.15 m
So total distance r = 0.70+0.15 = 0.85
We know that acceleration is given by
Here acceleration is acceleration due to gravity so a=g
So
So velocity will be 2.886 m/sec
Answer: The magnitude of the force is 5.4N
Explanation:
Answer:
50m; 0m/s.
Explanation:
Given the following data;
Initial velocity = 20m/s
Acceleration, a = - 4m/s²
Time, t = 5secs
To find the displacement, we would use the second equation of motion;
Substituting into the equation, we have;
Displacement, S = 50m
Next, to find the final velocity, we would use the third equation of motion;
Where;
<em>Substituting into the equation, we have;</em>
Final velocity, V = 0m/s
<em>Therefore, the displacement of the bus is 50m and its final velocity is 0m/s.</em>
