Q1. A car at the Indianapolis-500 accelerates uniformly from the pit area, going from rest to 325 km/h in a semicircular arc with a radius of 192 m.
find out the tangential acceleration of the car when it is halfway through the turn, assume constant tangential acceleration.
Q2. Recognize and sketch all the external forces acting on the chair. Because the chair can be represented as a point particle of mass, draw the forces with their tails centered on the black dot in the middle of chair. Be certain to draw the forces so that they have the accurate orientation.
