The position of a squirrel running in a park is given by r⃗ =[(0.280m/s)t+(0.0360m/s2)t2]i^+ (0.0190m/s3)t3j^.
What is υx(t), the x-component of the velocity of the squirrel, as function of time?
a.) vx(t)=(0.0720m/s2)t
b.) vx(t)=(0.280m/s)t+(0.0720m/s2)t2
c.) vx(t)=0.280m/s+(0.0720m/s2)t
d.) vx(t)=0.280m/s
