Aparticle moving at a velocity of 4.5 m/s in the positive x direction is given an acceleration of 7.1 m/s 2 in the positive y direction for 0.7 s. what is the final speed of the particle? answer in units of m/s.

The particle's velocity in the direction at time is

so that after 0.7 s, its velocity in the direction is

At this point, the particle has a velocity vector . Its speed will be the magnitude of this vector, which is given by

compass can be used day and night, cloudy or sunny
