A physics student monitors the speed and kinetic energy of a 0.36 kg traveling object that moves in a straight line. At a time of t = 1.00 s, the object is traveling with a speed of 5.0 m/s and at a time of t = 4.00 s, the object has a kinetic energy of 24 J. Determine the following. (a) Calculate the kinetic energy of the object (in J) at t = 1.00 s  J (b) Calculate the speed of the object (in m/s) at t = 4.00 s.  m/s (c) Calculate the work done on the object (in J) between t = 1.00 s and 4.00 s.  J (d) Calculate the distance (in m) that the object moves between t = 1.00 s and 4.00 s.  m (e) Calculate the average force (in N) exertec on the object between t = 1.00 s and 4.00 s.  N
