Calculating Acceleration: A Physics Exercise

What is the acceleration of a 10kg ball moving in a straight line?

The ball is measured to be moving at 4m/s initially. After 10 seconds, the speed increases to 9m/s.

Answer:

The acceleration of the 10kg ball, moving in a straight line, is calculated using the formula for acceleration: (Final velocity - Initial velocity) / time. In this case, it is (9m/s - 4m/s) / 10s, which equals 0.5 m/s².

The question is a classic example of a physics problem involving linear motion and specifically, acceleration. Acceleration is defined as the rate of change of velocity per unit of time. In this case, the initial velocity (vi) of the ball is 4 m/s and the final velocity (vf) after 10 seconds is 9 m/s.

To calculate the acceleration (a), we can use the formula a = (vf - vi) / t, where 't' is time. Inserting the given values into the equation, the acceleration is (9 m/s - 4 m/s) / 10s = 0.5 m/s². Therefore, the acceleration of the ball is 0.5 m/s².
