Question 2 1 pts For the same curve as above, x(t) = t cos(t/2), y(t) = t², z(t) = t sin(t/2), a student remembers the first year formula a = dv/dt and so tries to calculate the scalar acceleration a by calculating the derivative of the speed v. At time t = 3.19, let A be the percent error, the absolute value of the difference between this wrong calculation and the correct answer divided by the correct answer times 100. Then sin(A/2) is 0.772 -0.339 0.968 0.902 -0.048 0.711 0.442 -0.271
