To Find :
Position vector at time and
.
Solution :
r (t) = 2 (t −7)i + 12t j
Putting t = 5 s and t = 8 s, we get :
r(5) = 2( -2 )i + 60j
r(5) = -4i + 60j
r(8) = 2i + 96j
Now, to find speed differentiating the r(t) w.r.t t :
Hence, this is the required solution.
Answer:
Step-by-step explanation:
If we graphed y=1, then it would be a horizontal line where a point would be on (0,1).
A horizontal line has no slope, and the y-intercept for y=1 is one.
