An object undergoes acceleration 2.3i + 3.6j m/s^2 for 10s. At the end of this time, its velocity is 33i + 15j m/s.
A. what was its velocity at the beginning of the 10s interval?
B. By how much did its speed change?
C. by how much did its direction change?
D. show that the speed change is not given by the magnitude of the acceleration multiplied by the time. Why not?

An object with a mass of 5.69 kg undergoes an acceleration of -4.7 m/s^2 for a period of 5.8 seconds. It then undergoes an acceleration of 6.9 m/s^2 for a period of 8.7 seconds. If the initial velocity of the object is 1.51 m/s and it first experiences acceleration when it is at the origin, plot by hand a graph the force, velocity, and position as functions of time. Explain why your graph look the way they do and include...
