• An object travels along a straight path, So = 0 and Vo = 0, it's acceleration in m/s² as a function of time is given. Construct the s-t, v-t and a-t motion graphs. %3D (0.41 0st<10s @ a ={2.4 10 si<20s ® O 20
Short computation The velocity of an object as a function of time is given by v(t) = b = ct- et²2, where v and t are in SI units. The other variables are given as b = 4.1 m/s, c = 4.1 m/s², and e = 1.5 m/s³. Determine the instantaneous acceleration of the object at time t = 0.38 s. a m/s² Remember to include a "-" if the acceleration turns out to be negative. Do not include a "+" for a positive value. Report your numerical answer below, assuming three significant figures.
2. Juliet is trying to determine the height of her balcony from the base of the building without leaving her balcony. To do this, she asks Romeo for advice. Using concepts of physics that we have discussed in class, what advice should Romeo give to Juliet? Hint: Assume that Juliet has access to a timer and her reacting time to start and stop the timer is zero. Also, she has an object that she can drop and there is no air resistance. Clearly, explain your answer.
