Question

To this point we have been examining accelerations caused by the change in speed of an object. However, we must remember than acceleration can be caused by changing your direction without changing your speed, as when your automobile goes around a curve at constant speed. Thus if you change direction, you will have an accleration. This is due to the vector nature of velocity and acceleration. For this problem, consider a bicycle going north at 2 m/s. The cyclist then wants to go east at 2 m/s. If it takes him 2 seconds to transition from north to east, what is his acceleration. Question 13 options: 1 m/s/s 2 m/s/s in the southwest direction 1.4 m/s/s in the northeast direction 2.8 m/s/s in the southwest direction

Explanation / Answer

1.4 m/s/s in the northeast direction
