A 10.0 kg ball is released from rest in an ocean. As it falls, the water applies a resistive force R = −bv, where v is its velocity. At a time 6.14 s after its release, the ball is moving at half of its terminal speed. (Ignore any buoyant force.)
(a) What is the ball's terminal speed (in m/s)? m/s
(b) At what time after release (in s) is its speed three-fourths of its terminal speed? s
(c) How far (in m) has the ball moved in the first 6.14 s of its motion?

A 1.90 kg solid, uniform ball of radius 0.200 m is released from
rest at point A in the figure below, its center of gravity a
distance of 1.90 m above the ground. The ball rolls without
slipping to the bottom of an incline and back up to point B where
it is launched vertically into the air. The ball then rises to its
maximum height hmax at point C.

You toss a ball from a balcony. When the ball leaves your hand, it is 10.0 meters above the ground and has a velocity of (10.0 m/s, 45.0 degrees above the horizontal). Ignore air resistance. (let's take the x-direction to be aligned with the horizontal motion and the y-axis to be upward.) A) How high above the ground does the ball go, and how much time does it take to reach max height? B) Determine the total time of flight....

A small spherical ball of density p and radius a is released from rest and falls under gravity in a viscous liquid of density pf and viscosity u. Its vertical position is denoted by z(t), and we choose the origin such that z(0) = 0. The ball is subjected to two forces: its weight corrected for buoyancy F, = (p-p Vg, where g is the acceleration of gravity pointing in the - z direction and V = 47a/3 is the...
