Applied Dynamics - Assignment 10-6 Projectiles A projectile is fired at an angle of 30 degrees from the horizontal, with a velocity of 120 ft/s. If it lands 3.12 seconds later at the same elevation, how far did it travel horizontally?

Applied Dynamics - Assignment 10-6 Projectiles A projectile that is fired with an initial velocity of 275 m/s is inclined upward at an angle of 35 degrees. It lands at a point 120 m lower than the initial point. Determine the time of flight. Determine the horizontal displacement. Determine the final velocity at the point of landing.

Applied Dynamics - Assignment 11-2 Angular Displacement An ammeter needle, starting from a zero reading, deflects 50 degrees clockwise and then returns 10 degrees counterclockwise to indicate a final reading. What is the angular displacement and angular distance in terms of radians?

Applied Dynamics - Assignment 11-3 Angular Velocity The crankshaft of an engine turns 950 revolutions clockwise in 3 minutes at constant velocity. What is the angular velocity in rad/s?
