Determine a vector expression for the position of a particle whose velocity is (3t^2 - 8)i + 5j m/s.

r(t) = [integral] v(t) dt

      = (t^3 - 8t + C)i + (5t + C)j m

A 0.20 kg mass is whirled round in a vertical circle on the end of a light string of length 0.90 m. At the top point of the circle the speed of the mass is 8.2 m/s. What is the tension in the string at this point?


A body with speed v is projected from the surface of the earth(mass M & radius R). Find the maximum distance from the earth that this body reaches before returning back to earth, as a function of the initial speed v, M, R and the gravitational constant G
