A 5.42-kg object passes through the origin at time t = 0 such thatits x component of velocity is 4.65 m/s and its y component ofvelocity is -3.12 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 located at x = 8.50m and y = 5.00 m. What constant force acted on the object duringthis time interval?
magnitude=?
(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=? (measured from the +x axis )
(c) What is the speed of the particle at t = 2.00 s?
