determine the acceleration for a jet taking off on a run way as it starts from rest and reaches a velocity of 50m/s over a period of 10s
since v increased by 50m/s in 10s, that would be 50m/s / 10s = 5m/s^2 acceleration
im and Rick both can run at speed vr and walk at speed vw, with vr>vw. They set off together on a journey of distance D. Rick walks half of the distance and runs the other half. Tim walks half of the time and runs the other half
To determine the acceleration of the jet taking off, we can use the formula:
acceleration (a) = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 0 m/s (starting from rest)
Final velocity (v) = 50 m/s
Time (t) = 10 s
Plugging in the values into the formula:
a = (50 m/s - 0 m/s) / 10 s
a = 50 m/s / 10 s
a = 5 m/s²
Therefore, the acceleration of the jet taking off is 5 m/s².
To solve similar problems, you can follow these steps:
1. Identify the initial velocity (u), final velocity (v), and the time taken (t).
2. Use the formula: acceleration (a) = (v - u) / t.
3. Substitute the values into the formula and solve for acceleration.
4. Make sure to use the consistent unit for all values for accurate results.
