A particle moves in the xy plane with constant(adsbygoogle = window.adsbygoogle || []).push({});

acceleration. At time zero, the particle is at

x = 5.5 m, y = 2.5 m, and has velocity

ṽ=(2.5 m/s) î+ (−2 m/s)ĵ . The acceleration is

given by ā =(3 m/s2) î+ (7.5 m/s2)ĵ.

What is the x component of velocity after

2.5 s? Answer in units of m/s

What is the y component of velocity after

2.5 s? Answer in units of m/s

What is the magnitude of the displacement

from the origin (x = 0 m, y = 0 m) after

2.5 s? Answer in units of m

The use of velocity and accelration in terms of vector units( i,j coordinates) instead of a single numerical measurement has me confused, especially since it is not in my text book. Avy suggestions?
