A small rocket to gather weather data is launched straight up. Several seconds into the flight, its velocity is 140 m/s and it is accelerating at 20 m/s2 . At this instant, the rocket's mass is 51 kg and it is losing mass at the rate of 0.50 kg/s as it burns fuel. What is the net force on the rocket?

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r ร f) ยท n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, โ5, 4] n, r = [โ3, 5, 2] m, and n = [6, 5, โ7].
