7 of 15 ITI At any given time, 181 kg of water is falling at 31.6 m/s over the Canadian Falls. Use the conservation of energy theorem to determine how high the Canadian Falls must be? (Assume the water is in free fall with an initial speed of zero)

27. (II) A projectile is fired with an initial speed of 36.6 m/s at an angle of 42.2° above the horizontal on a long flat firing range. Determine (a) the maximum height reached by the projectile, (b) the total time in the air, (c) the total horizontal distance covered (that is, the range), and (d) the speed of the projectile 1.50 s after firing.

Two particles move perpendicular to each other until they collide. (Figure 1) Particle 1 has mass m and momentum of magnitude 2p, and particle 2 has mass 2m and momentum of magnitude p. Note: Magnitudes are not drawn to scale in any of the figures. Suppose that after the collision, the particles "trade" their momenta, as shown in the figure. That is, particle 1 now has magnitude of momentum p, and particle 2 has magnitude of momentum 2p; furthermore, each particle is now moving in the direction in which the other had been moving. How much kinetic energy, K lost, is lost in the collision? 1. 3p²/2m 2. 9p²/4m 3. 3p²/4m 4. 0 5. 1p²/4m
