A hot air balloon travels with the wind. The wind speed vector is V = -3i + 5j m / s for the first hour and then it is 5i + 2j m / s for 2 hours. In a system of coordinates (x, y), draw the current line when for a path of t = 2 hours if the globe part of the point (1,0) m.

A hot air balloon is rising straight up at a constant speed of 6.20 m/s. When the balloon is 12.0 m above the ground, a gun fires a pellet straight up from ground level with an initial speed of 28.9 m/s. Along the paths of the balloon and the pellet, there are two places where each of them has the same altitude at the same time. How far above the ground are these places? Enter the smaller altitude first.

You are in a hot-air balloon that ascends at a constant velocity of 2.75 m/s for 10 minutes. Your combined mass, you, the balloon and all of the balloon’s hardware, is 1350 kg. How much work is done against gravity during this ascent? What is the change in the gravitational potential energy of the hot-air balloon system? If you drop an object out of the balloon at rest with respect to the balloon, at what speed will it just strike...

What is the pressure gradient required to maintain a geostrophic wind at a speed of v = 10 m s?1 at 45? N? In the absence of a pressure gradient, show that air parcels flow around circles in an anticyclonic sense of radius v/f. I think that this is the answer to the first part ?p/?x = ?fv = 1 kg m?3 × 2 × 7.27 × 10?5 s?1 × sin (45?) × 10 m s^?1 = 1. 028 1...

When a derivative is taken of a VECTOR quantity, then the derivative of each COMPONENT is taken with respect to the same PARAMETER, i.e, d(x,y)/dt = (dx/dt,dy/dt). When objects travel on CURVED PATHS, and alternate RECTANGULAR description of the motion is the coordinates RELATIVE to the path. This has the advantage of immediately answering questions that are important to us: the TANGENTIAL component speeds up and slows down the object and the NORMAL component turns it. 1. A child rides...

A researcher hypothesizes that caffeine will affect the speed with which people read, but differently if people get a full night’s sleep (e.g., 8 hours) than if they do not get a full night’s sleep (e.g., 2 hours). To test this, the researcher randomly assigns 24 people into one of 6 conditions defined by fully crossing Factor A and Factor B: Factor A: 100 mg Caffeine (a1), 50mg Caffeine (a2) or Placebo (a3) Factor B: 8 hours of sleep (b1)...
