Given:
Initial velocity (u) = 10 m/s
Final velocity (v) = 20 m/s
Time interval (t) = 5 seconds
Using the formula for average velocity:
Average velocity (v_avg) = (v - u) / t
Substituting the given values:
v_avg = (20 - 10) / 5
= 10 / 5
= 2 m/s
Understanding average velocity:
Average velocity is the total displacement divided by the total time taken. It represents the overall change in position of the particle during the given time interval.
Determining displacement:
Displacement (s) = v_avg * t
Substituting the known values:
s = 2 * 5
= 10 m
Determining the velocity 3 seconds before:
To find the velocity 3 seconds before the given time interval, we need to subtract 3 seconds from the given time interval.
Calculating the time:
New time interval = t - 3
= 5 - 3
= 2 seconds
Determining the velocity:
Using the formula for average velocity again, we can find the velocity at 3 seconds before:
v_avg = (20 - u) / (t - 3)
Substituting the known values:
2 = (20 - u) / 2
Isolating 'u' (initial velocity):
20 - u = 4
u = 20 - 4
u = 16 m/s
Conclusion:
Therefore, the velocity of the particle 3 seconds before is 16 m/s.
Initial velocity (u) = 10 m/s
Final velocity (v) = 20 m/s
Time interval (t) = 5 seconds
Using the formula for average velocity:
Average velocity (v_avg) = (v - u) / t
Substituting the given values:
v_avg = (20 - 10) / 5
