1.A car, starting from rest, accelerates in the +x direction as in the figure. It has a mass of 1.10 10³ kg and maintains an acceleration of +4.40 m/s² for 5.40 s. Assume that a single horizontal force (not shown) accelerates the vehicle. Determine the average power generated by this force

2.A projectile of mass 0.641 kg is shot straight up with an initial speed of 26.1 m/s. (a) How high would it go if there were no air resistance? (b) If the projectile rises to a maximum height of only 7.10 m, determine the magnitude of the average force due to air resistance.
