A projectile is shot from the edge of a cliff 120 m above ground level with an initial speed of 60 m/s at an angle of 30.0o with the horizontal, as shown below. (a) How long does it take for the projectile to hit the ground? (b) How far does the projectile land from the base of the cliff? (c) What are the horizontal and the vertical components of its velocity when it hits the ground? (d) What are the magnitude of the velocity, and the angle made by the velocity vector with the horizontal. (e) What’s the maximum height above the cliff reached by the projectile. (f) How long does it take for the projectile to reach the maximum height?

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
