You're in an airplane that flies horizontally with speed 1200 km/h (320 m/s ) when an engine falls off. Neglecting air resistance, assume it takes 25 ss for the engine to hit the ground. a. Show that the plane is 4.5 km high.
b. Show that the horizontal distance that the aircraft engine falls is 8400 m.
c. If the airplane somehow continues to fly as if nothing had happened, where is the engine relative to the airplane at the moment the engine hits the ground?

The a992 steel rod bc has a diameter of 50 mm and is used as a strut to support the beam. determine the maximum intensity w of the uniform distributed load that can be applied to the beam without risk of causing the strut to buckle. take f.s. = 2 against bucklin

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Need only answer if you think you know it
