A JetBlue flight from Jacksonville, FL to San Diego is flying at 500 km per hour west. It encounters a head wind that is moving at 300 km per hour in an easterly direction towards the east. What is the net velocity of the plane, include directions?

Starting from rest, a(n)9 kg block slides 9.7 m down a frictionless ramp (inclined at 30◦ from the floor) to the bottom. The block then slides an additional 23.5 m along the floor before coming to stop. The acceleration of gravity is 9.8 m/s 2.Find the spee...

An american system of communication is based on the radio frequency of 76 Hz. Compute the wavelength of theses waves and compare it to the diameter of the earth.

An approaching train produces the RP1 signal (attention signal) at 600 Hz . The train moves with the speed of 120 km/h. What is the frequency and the wavelength of the sound detected by a person standing next to the track?

A bat­ watcher detects the sound of a hunting greater horseshoe bat at 76 kHz . She knows that this species produces echolocation calls at 80 kHz . What is the speed of this bat with respect to the bat­watcher? Is the bat receding or approaching?

The largest flying flag is 7410 sq ft and weighs 180 lbs. There are a total of 13 horizontal stripes on it. Let h represent the height of each stripe. What is the value of h?

confirm this is correct bec. when I check it, it doesn't add up the same. 13 - 3P = -5(3+ 2P) 13 - 3P = - 15 -10P 13 = -15 -7P 28/-7 = -7P/-7 -4 = P

number sence what multiplication fact can be found by using the arrays for 2*9 and 5*9

It appears critical information is missing. wouldn't we need to know the sq. ft area of the stripes and the length of the stripes? Also, this is an American flag; the sq ft area of the stars is critical but not given.
