Question

Question 2 A 11.0 g rifle bullet is fired with a speed of 380 m/s into a ballistic pendulum with mass 9.00 kg suspended from a cord 70.0 cm long. Part A Compute the initial kinetic energy of the bullet, K 794 J My Answers Give Up Correct Part B Compute the kinetic energy of the bullet and pendulum immediately after the bullet becomes embedded in the pendulum K 0.970 J Subm My Answers Give Up Correct Part C Compute the vertical height through which the pendulum rises. AE cm. Submit My Answers Give Up Incorrect; Try Again; 2 attempts remaining Provide Feedback

Explanation / Answer

Apply conservation of energy from embedding the bullet into pendulum to maximum height

K= mgh ; m=9+0.011 and g=9.8

h= 0.01 m
