Answer the following with full solution.
1. ) A shot is project 40° from the horizontal at the rate of 30 ft/s. (a) Find the maximum height (b) the maximum range of projectile.
2. ) A drop hammer of 1 ton weight capacity is projected downward by a 12 inch diameter cylinder. At 100 psi air pressure, what is the impact velocity if the stroke is 28 inches.
3.) A projectile is fired up the inclined plane at an initial velocity of 15 m/s. The plane is making an angle of 30° from the horizontal. If the projectile was fired at 30° from the incline, compute the maximum height z measured perpendicular to the incline that is reached by the projectile. Neglect air resistance.
Answer the following with full solution.
1.) A stone is thrown vertically up from the ground with a velocity of 400 ft per sec. How long must one wait before dropping a second stone from the top of an 800ft tower if the two stones are to pass each other 300 ft from the top of the tower?
2.) It was once recorded that a Jaguar left skid marks that were 290 m in length. Assuming that the Jaguar skidded to a stop with a constant acceleration of -3.90 m/s², determine the speed of the Jaguar before it began to skid.
3.) A capsule orbit the earth at the rate of 6000 m/s. If the radius of the Earth is 3000km, find the height of capsule from the surface of the Earth.
