The acceleration function (in m/s2) and the initial velocity are given for a particle moving along a line. a (t) = t + 6, v (0) = 3, 0 ≤ t ≤ 11 (a) Find the velocity at time t. v (t) = Correct: Your answer is correct.

A person with a mass of 75 kg skis from rest down a slope at an angle of 31 degrees. The coefficient of kinetic friction of his skis on the snow is 0.095. What is his acceleration?

A velocity vs. time graph for an object is shown. A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 5, velocity in meters per second on the y axis, numbered 0 to 5. A line starts at the origin and ends at (5, 5).
