If we find v = Aλ, where λ is a length and v is a speed, what are the standard metric units for the A?

Janice throws a stone horizontally from the roof edge of a 50. meter high dormitory.  Its hits the ground at a point 60. meter from the building.  What was the initial velocity?

A fan blade, whose diameter is 1.0 m, is turning with an angular velocity of 2.0 rad/s.  What is the tangential velocity of a point on the tip of the blade?

A motorcycle stunt rider wants to jump a 179 m wide canyon.  He arranges a ramp on one side so he will be launched pointed 30.o above the horizontal.  What minimum speed will be needed to just reach to the other side?

A projectile is fired horizontally in a region of no air resistance.  The projectile maintains its horizontal component of speed because it

Assuming negligible friction, what spring constant would be needed by the spring in a “B-B gun” to fire a 10. gram pellet to a height of 100 meters if the spring is initially compressed 10. cm?

An object is moving with a constant velocity.  Which statement MUST be TRUE?

A small bomb, of mass 10. kg, is moving toward the North with a velocity of 5.0 m/s.  It explodes into three fragments:  a 5.0 kg fragment moving West with a speed of 8.0 m/s; a 4.0 kg fragment moving East with a speed of 10. m/s; and third fragment with a mass of 1.0 kg.  What is the velocity of the third fragment?  (Neglect air resistance.)
