The velocity in ft/s of an object moving along a line is given byv = ƒ(t) on the interval 0 ≤ t ≤ 6 (see figure), where t ismeasured in seconds.a. Divide the interval [0, 6] into n = 3 subintervals, [0, 2], [2, 4],and [4, 6]. On each subinterval, assume the object moves at aconstant velocity equal to the value of v evaluated at the leftendpoint of the subinterval, and use these approximations toestimate the displacement of the object on [0, 6] b. Repeat part (a) for n = 6 subintervals
A car moves along a straight road. It moves at a speed of 50 km/hr for 4 minutes, then
during the next 4 minutes it gradually speeds up to 100 km/hr, continues at this speed
for 4 minutes, then takes 4 minutes to gradually slow to a complete stop. Make a
sketch like the figures in Section 1.2 of your textbook, marking dots for the position
along the road every minute.
An object's position in the as a function of time obeys the equation;
x(t) = 14.2/t2.17 + 5.1t3
where all constants have proper SI Units.
What is the speed of the object in the x direction at t = 1.93 seconds?
