A student kicks a 2 kg soccer ball with a force of 50 N. Calculate the acceleration of the soccer ball. Please show your work.(2 points)
To calculate the acceleration of the soccer ball, we can use Newton's second law of motion, which states:
F = m * a
Where:
F = force applied (50 N)
m = mass of the soccer ball (2 kg)
a = acceleration
Now, we can rearrange the formula to solve for acceleration:
a = F / m
a = 50 N / 2 kg
a = 25 m/s^2
Therefore, the acceleration of the soccer ball is 25 m/s^2.
