9 Required information An airplane has a mass of 48,000 kg, a wing area of 340 m*, a maximum lift coefficient of 3.2, and a cruising drag coefficient of O.03 at an altitude of 12.000 m. Take the density of standard air as p1-1225 kg/m3 at sea level and p2 0.312 kg/m at 12,000 m altitude. Determine the safe takeoff speed at sea level, assuming it is 20 percent over the stall speed The safe takeoff speed at sea level...
Problem: A spaceship of mass 1.9×106 kg is cruising at a speed of 6.0×106 m/s when the antimatter reactor fails, blowing the ship into three pieces. The first piece, having a mass of 4.9×105 kg , is blown straight backward with a speed of 2.5×106 m/s . A second piece, with mass 7.5×105 kg , continues forward at 1.0×106 m/s. Q: What is the speed of the third piece?
Consider the Figure below. The speed of the container N is: 2030 mm/sec M . N
An elevator weighing 2500 N ascends at a constant speed of 8.0 m/s. How much power must the motor supply to do this?

Cogepods have a slow cruising speed and also can make very rapid jumps, yet their antennae are not involved. two features possessed by copepods are used in performing these two different types of movements Discuss

7.) A Cessna 152 is a small airplane with a mass of 725 kg and a wing area of 15.0 m. It the wings are designed so that the air flows 13.5% faster above the wings than below, then what is the minimum cruising speed of the plane? (You can make the assumption that all the litt force comes from this difference in air flow.)
