Answer to Question #318527 in Mechanics | Relativity for Joshua

Question

7. ) 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.

8. ) 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.

9.) 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.
