rabbit run across a parking lot on which set of coordinates axes has been drawn. The coordinates (in metres) of the rabbits position as function of time (in second) are given by:-
x= -0.32t² + 7.2t + 28
y= 0.22t² - 9.1t + 30
At t=15 s, what is the rabbits position for r in unit vector notation and in magnitude angle notation?
i. Draw a graph for rabbits path for t= 0 to t= 25 s
ii. Find the rabbits velocity v at time t= 15 s
iii. Find the rabbits acceleration 'a' at time t= 15 s.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
