A(n) 78 g particlemoving with aninitial speed of 24 m/s in the positive xdirection strikes and sticks to a(n) 82 gparticle moving with 150 m/s in the positivey direction. How much kinetic energy is lost in this collision? Answer inunits of J.
Suppose that a police car on the highway is moving to the right at 30 m/s, while a speeder is coming up from almost directly behind at a speed of 31 m/s, both speeds being with respect to the ground. The police officer aims a radar gun at the speeder..
A cannon fires up at an angle 60 degrees above horizontal with a muzzle velocity of 60 m/s. What is the speed at the top of the cannonballs trajectory?
two long parallel wires each with a mass per unit length of 44 gm are supported in a horizontal plane by 6.0-cm-long
A diver comes off a board with arms straight up and legs straight down, giving her a moment of inertia about her rotation axis of 19.5 kg · m2. She then tucks into a small ball, decreasing this moment of inertia to 3.65 kg · m2. While tucked, she mak..
