Q.4. A robot lands on Mars. Its x and y coordinates are given by equations:
x(t) = 2m –(0.25m/s2
)t2
y(t)= (1.0 m/s)t +(0.025m/s3
)
(a).What is the position and distance from landing at t=2 seconds?(b)What is the
displacement and average velocity during the interval from t=0 s to t= 2?(c).Derive
a general expression for its instantaneous velocity vector and find its instantaneous
velocity in its component form as well as in terms of its magnitude.
a)
b)
c)
