13.

A bowling ball is dropped from a boat so that it strikes the surface of a lake with a speed of 8 m/s. Assuming the ball experiences a downward acceleration of a = 3 - 0.1v2 when in the water, determine the velocity of the ball when it strikes the bottom of the lake. (a and v expressed in m/s2 and m/s respectively). Which integral should you choose?

a)

$\int_{x_o}^x\ dx\ =\int_{v_o}^v\ \frac{v\ dv}{a\left(v\right)}$
