If a projectile is fired from the origin of the coordinate system with an initial velocity υ0 and in a direction making an angle α with the horizontal, calculate the time required for the projectile to cross a line passing through the origin and making an angle β < α with the horizontal.
A fireman, 50.0 m away from a burning building, directs a stream of water from a fire hose at an angle of 30.0 ° above the horizontal. If the initial speed of the stream is 40.0 m/s, at what height will the stream of water strike the building? a.9.60 m b.18.7 m c.13.4 m d.22.4 m
In Fig, a slab of mass m1 =40 kg rests on a frictionless floor, and a block of mass m2 =10kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40. A horizontal force of magnitude 100 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab?

A projectile is fired horizontally to the west at a velocity of 21 m/s.
A diver explores a shallow reef off the coast of Belize. She initially swims 90.0 m north, makes a turn to the east and continues for 200.0 m, then follows a big grouper for 80.0 m in the direction 30° north of east. In the meantime, a local current displaces her by 150.0 m south. Assuming the current is no longer present, in what direction and how far should she now swim to come back to the point where she started?
A bullet is fired with initial velocity of 100 m/s from the hill at point P at an angle of 30° with the horizontal and it strikes at 80 m lower than P. Neglecting air resistance and by using the concept of linear and curvilinear motion, find (a) the horizontal distance from the gun to the point where the projectile strikes the ground, (b) the greatest elevation above the ground reached by the projectile.
