Final answer:
To calculate the proton's acceleration, we need to use the formula acceleration = (final velocity - initial velocity) / time taken.
Step-by-step explanation:
To calculate the proton's acceleration, we need to use the formula acceleration = (final velocity - initial velocity) / time taken. In this case, the proton's initial velocity is 2.00 x 10^5 m/s and its final velocity is 9.00 x 10^5 m/s. The distance traveled is 10.0 cm, which is equal to 0.1 m. The time taken can be calculated using the formula distance = 0.5 × acceleration × time^2. Therefore, the acceleration of the proton is (9.00 x 10^5 - 2.00 x 10^5) / time taken.
