Question

I tried to do the practice problem but I don't know what I am doing wrong.

6. 12 points OSUniPhys1 3.2.WA 019. My Notes Ask Your Teacher The position of a particle moving along the x axis with a constant acceleration may be determined from the expression x(t) = b + c(t-2 s)2, where b = 4.00 m, c = 6.00 m/s2, and x will be in meters when t is in seconds. Determine the following. (Where applicable, indicated direction with the sign of your answer.) (a) position, velocity, and speed of the particle at the time t = 0 s (Enter your answers to at least one decinnal place.) position xtt os) velocity v(t = 0 s) m/s speed v(t = 0 s) = m/s (b) position, velocity, and speed of the particle at the time t-4 s (Enter your answers to at least one decimal place.) position x(t 4 s) = velocity v(t-4 s) m/s speed v(t- 4 s) m/s (c) time and position of the particle when it changes direction (Enter your answers to at least one decimal place.) tchange) (d) displacement, distance traveled, average velocity, and average speed of the particle over the time interval t = 0 → 4 s change displacement Δx(t = 0 → 4 s)- distance dt-0 average velocity v(-4 s) - average speed v(t = 0 → 4 s) 4 s) m/s m/s Additional Materials
