Answer:
first find the area of the triangle
1/2 base x height
(1/2) 6 x 4 = (1/2) (24) = 12
area of rectangle
base x height
4 x 6 = 24
add them together
24 + 12 = 36
B) 36 inches
hope this helps :)
Step-by-step explanation:
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.
