an object is moving up and inclined plane its velocity changes from 15 cm\sec to 10 cm\sec in 2 seconds .what is its acceleration solve
a = change in velocity/change in time
= -5 cm/ 2 s^2 = -3.5 cm/s^2 = -.035 m/s^2
To find the acceleration of the object moving up an inclined plane, we can use the formula:
acceleration = (final velocity - initial velocity) / time
Given that the initial velocity (u) is 15 cm/sec, the final velocity (v) is 10 cm/sec, and the time (t) is 2 seconds, we can now substitute these values into the formula:
acceleration = (10 cm/sec - 15 cm/sec) / 2 seconds
Now, we can simplify the equation:
acceleration = -5 cm/sec / 2 seconds
The negative sign indicates that the object's velocity is decreasing. Finally, we can calculate the acceleration:
acceleration = -2.5 cm/sec^2
Therefore, the acceleration of the object moving up the inclined plane is -2.5 cm/sec^2.
