The archerfish hunts by dislodging an unsuspecting insect from its resting place with a stream of water expelled from the fish's mouth. Suppose the archerfish squirts water with a speed of 2.15m/s at an angle of 46.0 ^\circ above the horizontal, and aims for a beetle on a leaf 2.50cm above the water's surface.

At what horizontal distance from the beetle should the archerfish fire if it is to hit its target in the least time?
How much time will the beetle have to react?

What is the magnitude of the acceleration of the block : A block with mass m1 = 9.4 kg is on an incline with an angle ? = 24.0° with respect to the horizontal. For the first question there is no friction, but for the rest of this problem the coefficients of friction are: ?k = 0.23 and ?s = 0.253. 1) When t..

Find the speed at which the ball was launched : A playground is on the flat roof of a city school, 5.4 m above the street below (see figure). The vertical wall of the building is h = 6.90 m high, forming a 1.5-m-high railing around the playground. A ball has fallen to the street below, and a pa..
