A 5.75 kg object passes through the origin at time t=0 such that its x component of velocity is 5.00 m/s and its y component of velocity is -3.00 m/s. (a) What is the kinetic energy of the object at this time? (b) At a later time t=2.00 s, the particle is lovated at x= 8.50 m and y= 5.00 m. What constant force acted on the object during this time interval (vector notation)? (c) What is the speed of the particle at t= 2.00 s?
