The two rockets are timed to explode simultaneously at a height of 300 m as A is falling and B is ris- ing. Assuming a constant acceleration g = 9.81 m/s², determine (a) the time t₁, (b) the velocity of B relative to A at the time of the explosion.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

A soldier fires a round from a grenade launcher as his Humvee is moving up a 12° incline at VH = 31 m/s. He notes that at the moment he pulls the trigger, the vehicle has traveled d = 700 m from the base of the hill, and that his launcher is approximately 5 ft off the ground. The muzzle velocity of a grenade round is approximately v = 80 m/s. (figure not to scale) (a) Write equations of motion for the grenade (you should have two; one for x-position and one for y-position). Use a fixed frame of reference, with the origin located at the grenade's position at the moment it leaves the launcher. Your equations should be in terms of t and the launcher angle 82. (Hint: you will not need the launcher height or vehicle distance for this part.) d = 700 m 9,= 12° 8₂ Ⓒ € VH

Suppose a fly orbits you (on the horizontal plane) with a constant orbital radius of 5 meters and subject to a time-varying (tangential) acceleration given by the expression a ( t ) =1+t with an initial speed of 2 m/s. Since the fly remains a constant distance away from you, you cannot use your flyswatter the way you would like to. Suppose that you can throw your flyswatter with an initial speed of 15 m/s in any direction you want. If you throw at t=0, how, exactly, should you throw your flyswatter to hit the fly? (Give both the angle above the horizontal to throw your flyswatter –and- at what angle ahead of the fly to throw it). ..
