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.
An object moves so that its position depends on time as x=−10m+(5m/s)t+(2.5m/s2)t2. Which statement below is not true? a) The object never stops moving. b) The object first moves in the negative direction and then in the positive direction c) The object is accelerating d) The speed of the object is always increasing Which answer is correct and why?
Question 2 x (m) Figure below shows the position of an object moves along the x-axis. What is the object's velocity at 2.0 s, in m/s? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 20 10 0 0 2 3 4 1 points -t (s) Save Answer
A skier starts from rest down a slope 500.0 m long. The skier accelerates at a constant rate of 2.00 m/s squared. • a. Find the velocity of the skier at the bottom of the slope. Do this by deriving two separate equations for time and then making the expressions equal to each other to solve for the second velocity. • b. Using the distance down the hill, and the two velocities, determine the time it took to descend the hill.
