A 5.57-kg object passes through the origin at time t = 0 such that its x component of velocity is 5.25 m/s and its y component of velocity is -3.15 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 = 8.50 m and y = 5.00 m. What constant force acted on the object during this time interval?

magnitude

magnitude

Degrees?

(c) What is the speed of the particle at t = 2.00 s?

m/s

A) i got correct which is 104

B) i got 10.5

and 30.5 degrees which its telling me im off by10%

C) i need be corrected i think
