Calculate the depth of the lake

Reference no: EM13499776

A ball is dropped from a boat so that it striks the surface of a lake iwth a speed of 16.5 ft/s. Ball experiences aceeleration a = 10 - .8v, where a and v are expressed in ft/s^2 and ft/s. It takes 3 seconds for the ball to reach the bottom of the lake. Determin

a) the depth of the lake,

b) the final velocity.
