I need help in calculating the average time squared. Trial 1 = 1.20 s Trial 2 = 1.22 s Trial 3 = 1.32 s all for distance 0.3 m I have the average time for that (1.20 + 1.22 + 1.32)/3 I would like to understand how to calculate the square of the average time so I can continue with the other distances that I have.

An SUV travels a 1.30 km levelled road from Bonifacio Rotunda to Citylights Hotel ig a minimum time of 45.60 sec. The SUV starts from rest at the Rotunda, travels at constant speed for some time and will stop at Citylights Hotel. Given that the car accelerates and decelerates at 2.53 m/s, determine: a. The maximum speed (in kph) b. The time (in seconds) it travels at this speed. Assume that the time for accelerating and decelerating are equal.

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.
