Question 35 (1 point) A spring has an elastic constant of 4.40x104 N/m. What is the change in elastic potential energy stored in the spring when its stretch is increased from 12.5 cm to 15.0 cm? Q 1.51 x 10"6J Question 34 (1 point) ~/ Saved A 2.50 kg pendulum is pulled back and released from rest. If the maximum speed of the pendulum bob is 6.26 m/s, the height at which the pendulum was released, relative to the equilibrium position, is 2.00 m. Question 12 (1 point) A test mass placed at a point in space above Earth and experiences 0.91N/kg gravitational field strength. When the test mass is released, it will 0 move with constant velocity toward Earth O move at constant acceleration toward Earth 0 move with increasing acceleration toward Earth 0 remain at rest Question 24 (1 point) What is the period of a vibrating spring (spring constant = 100 Mm) if a mass of 500 g is hung from the spring
