1. The problem statement, all variables and given/known data A truck drives along a straight line, which we will call the x-axis with the positive direction to the right. The equation for the turtle's position as a function of time is: x(t) = 50.0cm + (2.00cm/s)t - (.0625cm/s^2)t^2 Find initial velocity: Find initial acceleration: Find initial position: 2. Relevant equations 3. The attempt at a solution I found that initial velocity is 2.00cm/s, as the equation states that V0 is initial velocity. I found initial position, by knowing that if time was zero, then the obvious would be to have it at 50cm. The acceleration is giving me the problem, I would think that it was .0625cm/s^2, but it is wrong. Then I would guess that since the initial velocity is 2.00cm/s then, acceleration at that point in time might be the same...is this right? I found this equation for instantaneous acceleration in which a= delta vx / delta t. So this would be 2.00cm/s / 0 = 0 acceleration?
