Find radial and transverse components of particle-s velocity
A particle moves in the x-y plane such that its postion is defined by r=[(2t)i+(4t^2)j]ft, where t is in seconds. Determine the radial and transverse components of the particle's velocity and acceleration when t=2s.

When the ball hits the wall, the horizontal component of its velocity is reversed; the vertical component remains unchanged. (Ignore any effects due to air resistance.)How long was the ball in the air before it hit the wall?
A 4.58 kg block located on a horizontal frictionless floor is pulled by a cord that exerts a force F=11.40 N at an angle theta=30.0 degrees above the horizontal. What is the speed of the block 5.50 seconds after it starts moving?
Boiling water at atmospheric pressure is often not enough to kill bacteria. Some bacteria can survive up to 120 degrees C. Sterilization is often performed by pressurizing water to increase its boiling point.
