Q. A 2100 kg car traveling to the right at 32 m/s is chasing a second car of the same mass that is traveling to the right at 10 m/s.
(a) If the two cars collide and stick together, what is their speed just after the collision?
(b) What fraction of the initial kinetic energy of the cars is lost during this collision?
Sources A and B emit long-range radio waves of wavelength 530 m, with phase of the emission from A ahead of that from source B by 90°. The distance rA from A to a detector is greater than corresponding distance rB from B by 110 m. What is the magni..
A diver is planning to salvage a Spanish galleon located in 200 feet of water. He plans to use a diving suit that will be supplied with air from a hose. Calculate which compressor should be bought by the diver for the given condition
The collar C is moving downward with an acceleration of 1 m/s2. At the instant shown, it has a speed of 2 m/s which gives links CB and AB an angular velocity ωAB = ωCB = 10 rad/s. Determine the angular accelerations of CB and AB at this instant.
Establish the wave functions and the general expression
When Babe Ruth hit a homer over the 7.5 -high right-field fence 98 from home plate, roughly what was the minimum speed of the ball when it left the bat? Assume the ball was hit 1.4 above the ground and its path initially made a 37 angle with the grou..
