A spring-block system executes simple harmonic motion. The mass of the block is m = 12 kg and the total energy is E = 18 J. The amplitude is A = 0:10 m.
(a) Find the spring constant.
(b) Find the maximum speed and the maximum acceleration.
(c) What is the total distance traveled by the block over one complete period?
(d) What is the total displacement of the block over one complete period?
You drive on Interstate 10 from San Antonio to Houston, half the time at 50 km/h and the other half at 88 km/h. On the way back you travel half the distance at 50 km/h and the other half at 88 km/h. (a) What is your average speed from San Antonio to ..
The drawing below shows an inverted "A" that is suspended from the ceiling by two vertical ropes. Each leg of the "A" has alengh of 2L and a weight of 120.0 N. The horizantal crossbar has a negligible weight. Find the force that the crossbar applies ..
