A motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average velocity in in the northern direction vavg,N, in this period in meters per second? 2. If the motorcycle's final velocity at tf was 12 m/s, what was the motorcycle's average acceleration in the northern direction, aavg,N, during this period in m/s2?
In class, we used a numerical method to determine the velocity of an object at 0s and = t = 2.00 s given that the object had started from rest at t accelerated at a rate given by a(t) = (8.00 m/s^)t². Here's what we did: 1. Divided t into four intervals of 0.5 s each. 2. For each interval, calculated the average a. These were the numerical values we obtained for each time interval: 1 0.25 0.50 i t (s) a; (m/s²) After summing the values according to: 2 0.75 4.50 3 1.25 12.50 lim ã‚At, 2 V₂v₁ = limast. t₁ At→0 we arrived at the approximate value v = 21.0 m/s. 4 1.75 24.50 a (m/s²) 32.00+ 24.00 16.00 8.00 0 ā₁ 0 ā2 az as 0.50 1.00 1.50 2.00 t (s) 21.33 m/s. We then proceeded to integrate to obtain the analytical solution, which was v = Using the same numerical method, divide t into eight and then sixteen intervals to calculate the approximate value for v at t = 2.00 s. This should demonstrate that with more sampling, the AUC (area under the curve) value converges toward the analytical…

Kinematic Universe. Which of the following is/are ALWAYS TRUE? I. Displacement is a vector quantity that has a magnitude and direction that depends on the path taken. II. Average velocity is equal to instantaneous velocity when the acceleration is zero. II. Instantaneous velocity is the slope of the tangent line in the velocity vs. time graph.
