Forces: Problem 4 (4 points) A 1.2 kg cannonball is fired from a 60 kg cannon. The cannonball accelerates out of the cannon at 619 m/s2 [forward] for 0.11 s. a) What is the acceleration of the cannon? (Assuming no friction) -12.380m/s^2 [forward] b) If the cannon has a coefficient of friction of 0.2, what force of friction does it experience? 117.600N c) Given the friction above, how fast is the cannon travelling after accelerating? 1.146m/s d) Given the friction above, what total distance will the cannon recoil? (Include units in your answer. Round your answer to three decimal places!) Hint
