The wave y1 = 0.12 sin π/3(5x+200t-1) propagates on a string of linear density 0.02 kg/m. (a) Calculate the average power transmitted. (b) If the wave y2 = 0.12 sin π /3(5x+200t+3)...

Having traveled the first 0.50 of the distance of your trip at an average speed of 30.0 km/hr, how fast must you travel for the rest of the trip in order to average 35.0 km/hr?

A car starts from rest and travels for 7.0 s with a uniform acceleration of +2.4 m/s2. The driver then applies the brakes, causing a uniform acceleration of -1.0 m/s2. If the brakes are applied...
