What is the average speed of the walker for this distance in km/h? km/h 5. DETAILS A tortoise and a hare cover the same distance in a race. The hare goes very fast for brief intervals, but stops frequently, whereas the t hare. (a) Which of the two racers has the greater average speed over the duration of the race? OThe tortoise has the greater average speed since he was the winner. The hare has the greater average speed since he can go faster. Their average speeds are equal. OIt's impossible to determine who had the greater average speed without collecting data. (b) Which of the two racers is likely to reach the greatest instantaneous speed during the race? OThe tortoise has the greater instantaneous speed since he was the winner. OThe hare has the greater instantaneous speed since he can go faster.
The velocity (v) in metres per second of an object in terms of the time (t) in seconds is given by: v = -10t2 + 9 The displacement of the object at time t=1 is -5m. What is the displacement of the object (in m) at time t=3 to 2 d.p.?
The displacement of a particle is given by s = 4t³ - 60t² + 100t -58 where s is in feet and t is in seconds. Plot the displacement, velocity, and acceleration as functions of time for the first 13 seconds of motion. After you have made the plots, answer the questions. Questions: At t = 1.8 S= i fty = i ft/seca = i ft/ser sec, At t = 6.6 i S= fty = i ft/seca = i ft/se sec, Att = 9.8 sec, i fty = ft/seca = S = i ft/ser The velocity is zero when t = i sec and when t = sec

An object is moving in the air (defying gravity) so that its height after t seconds is given by ℎ(t)=18sin(t)cos(t)+8t meters. (If you graph this function, you can see it's moving up and down, but going higher and higher as time goes on.) a) At what time, t, does the object first change direction from going up to going down? b) What is the acceleration (m/s^2) of the object at that same time?
