Question
1. A 283 g air track glider moving at 0.69 m/s on a 2.4 m long air track collides elastically with a 467 g glider at rest in the middle of the horizontal track. The end of the track over which the struck glider moves is not frictionless, and the glider moves with a coefficient of friciton m = 0.02 with respect to the track. Will the glider reach the end of the track? Neglect the length of the gliders. 2. A block sldes on a semicircular fricitonless track as shown. a) If it starts from rest at point A, what is its speed when it reaches the bottom of the track at point B? b) What force does the track exert on the block when it passes through point B if the block's mass is 1.00 kg? 3. A tennis ball starting from rest, rolls down the hill in the drawing. At the end of the hill the ball becomes airborne, leaving at an angle of 35o with respect to the ground. Treat the ball as a thin-walled spherical shell, and determine the range x. 4. A 10.1 kg uniform board is wedged into a corner and held by a spring at a 50.0o angle, as the drawing shows. The spring has a spring constant of 176 N/m and is parallel to the floor. Find the amount by which the spring is stretched from its unstrained length. 5. A spherical balloon is made from a material whose mass is 3.00 kg. The thickness of the material is negligible compared to the 1.50 m radius of the balloon. The balloon is filled with helium at a temperature of 305 K and just floats in air, neither rising nor falling. The density of the surrounding air is 1.19 kg/m3. Find the pressure of the helium gas assuming it is ideal.Explanation / Answer
