Michelle rode her bicycle from her house to her school at an average speed of 8 miles per hour (mph). Later that day, she rode from school back home along the same route, at an average speed of 12 mph. If the round trip took her 1 hour, how many miles lon...

Two people are pulling a mule. One is pulling at 120 N* at 60 degrees, and the other is pulling at 80 N* at 105 degrees. Find: a) The single force that is equivalent to the forces shown. AND b) The force that a third person would have to exert on the mule...

Three Displacement Vectors of a Croquet Ball are shown, where A is 20.0 units at 90 degrees, B is 40.0 units at 45.0 degrees, and C is 30.0 at 315 degrees. Find: a) The resultant in unit-vector notation. AND b) The magnitude and direction of the resultant...

A train slows down as it rounds a sharp bend, slowing from 90.0km/h to 50.0km/h in the 15.0s that it takes to round the bend. The radius of the curve is 150m. Compute the acceleration at the moment the train speed reaches 50.0km/h. Assume it continues to...

Solve the question: sin(2x)=cos(x), for values of x between 0 and 2 Pi

How did you find the speed reduction?

Converted to m/s, I presume?
