Use the equation for the motion of an accelerating object to answer the question.
x=x0+v0t+12at2
Which equation could describe the motion of an object starting at x=0
with a starting speed of 10 m/s and an acceleration of 3 m/s2?
1.x=1.5+10t
2. x=3+5t2
3. x=10t+1.5t2
4. x=5+3t
The correct equation that could describe the motion of an object with the given conditions is:
3. x=10t+1.5t^2
This equation matches the general form of the equation for the motion of an accelerating object, with x0 (initial position) being 0, v0 (initial velocity) being 10 m/s, and a (acceleration) being 3 m/s^2.
