A spherical bowling ball with mass m = 4.6 kg and radius R = 0.105 m is thrown down the lane with an initial speed of v = 9.5 m/s. The coefficient of static friction between the ball and the ground is 0.35 and the coefficient for kinetic friction is μ = 0.3. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) What is the magnitude of the angular acceleration of the bowling ball as it slides down the lane? 2) What is magnitude of the linear acceleration of the bowling ball as it slides down the lane? 3) How long does it take the bowling ball to begin rolling without slipping? 4) Once it begins to roll without slipping, what is the force of friction on the ball?

graduate who joined the Navy as a pilot is about to take off in an F-15 (WF15 = 81,000 lb) from an aircraft carrier traveling at VA = 40 mph. The jet is launched from the catapult system (a connection just below the deck that assists the aircraft) with the force (Fcp) vs time curve shown that has points of F₁ = 1,000 lb at t₁ = 2 s and F₂ = 3,000 lb at t₂ = 5 s (the plane will reach the edge of the deck at t₂). The F-15 needs to be traveling at 170 mph to take off. Determine how much constant thrust (FTR) the engines must produce during the launch to reach this speed. F2 F₁ FCP t₁ VA t₂ FTR t (s)
