4. The race car travels around the circular track with a speed of 16 m/s. When it reaches point A it increases its speed at a (4) m/s2, where v is in m/s. Determine the magnitudes of the velocity and acceleration of the car when it reaches point B. Also, how much time is required for it to travel from A to B? 200 m Figure: 12 P155

Constants Learning Goal: To practice Problem-Solving Strategy 6.1 Work and Kinetic Energy. Your cat Goldie (mass 7.90 kg ) is trying to make it to the top of a frictionless ramp 7.640 m long and inclined 33.0 ∘ above the horizontal. Since Goldie can’t get any traction on the ramp, you push her up the entire length of the ramp by exerting a constant 41.00 N force parallel to the ramp (there is a set of stairs alongside the frictionless...
