AP Physics C: Mechanics — Sample

A particle moves along the x-axis. Its acceleration is given by $ a(t) = (6t - 12) \text{ m/s}^2 $. At time $ t=0 \text{ s} $, the particle's velocity is $ v(0) = 10 \text{ m/s} $ and its position is $ x(0) = 5 \text{ m} $. What is the position of the particle at $ t=3 \text{ s} $?

A 3 m

B 8 m

C 21.5 m

D -22 m

Explanation. The correct answer is 8 m. To find the position $ x(t) $ from the acceleration function $ a(t) $, you must integrate twice. First, integrate $ a(t) $ to find the velocity function $ v(t) $. Given $ a(t) = 6t - 12 $, $ v(t) = \int (6t - 12) dt = 3t^2 - 12t + C_1 $. Using the initial condition $ v(0) = 10 \text{ m/s} $, you find $ C_1 = 10 $. So, $ v(t) = 3t^2 - 12t + 10 $. Next, i
