AP Physics 1 Exam Question

A 2 kg object is initially at rest on a frictionless surface. A constant force of 10 N is applied to the object for a duration of 2 seconds. Determine the acceleration of the object using Newton's laws of motion.

Solution To determine the acceleration of the object, we can use Newton's second law of motion:

F = m * a

where F is the force applied to the object, m is the mass of the object, and a is the acceleration.

Given: Force, F = 10 N Mass, m = 2 kg Time, t = 2 s

Using Newton's second law, we can rearrange the equation to solve for acceleration:

a = F / m

Substituting the given values into the equation:

a = 10 N / 2 kg

a = 5 m/s^2

Hence, the acceleration of the object is 5 m/s^2.
