A 5.37-kg object passes through the origin at time t = 0 such thatits x component of velocity is 4.60 m/s and its y component ofvelocity is -3.06 m/s.
(a) What is the kinetic energy of the object at this time?
?J
(b) At a later time t = 2.00 s, the particle is located at x = 8.50m and y = 5.00 m. What constant force acted on the object duringthis time interval?
magnitude ? N
direction ? ° measured from the +x axis
(c) What is the speed of the particle at t = 2.00 s?
? m/s
