A simple pendulum, 2.00 m in length, is released from rest when the support string is at an angle of 35.0° from the vertical. What is the speed of the suspended mass at the bottom of the swing? (g = 9.80 m/s2 and ignore air resistance)Select one:a.1.33 m/sb.1.88 m/sc.0.941 m/sd.2.66 m/s

A 0.440-kg pendulum bob passes through the lowest part of its path at a speed of 3.38 m/s.(a) What is the magnitude of the tension in the pendulum cable at this point if the pendulum is 77.0 cm long? Your response differs from the correct answer by more than 10%. Double check your calculations. N(b) When the pendulum reaches its highest point, what angle does the cable make with the vertical? (Enter your answer to at least one decimal place.) Your response differs from the correct answer by more than 10%. Double check your calculations.°(c) What is the magnitude of the tension in the pendulum cable when the pendulum reaches its highest point? Your response differs from the correct answer by more than 100%. N
