A Two carts are set in motion at t : 0 on a frictionless track in a physics laboratory. The first cart is launched from an initial position of x : 17.0 cm with an initial velocity 0f13.0l cm/s and a constant ac of 73.50;" cm/sz. The second cart is launched from X = 19.4 cm with a constant velocity of 4.40? cm/s. (a) What are the times for which the two caits have equal speeds? earliertime |:|s (b) What are the speeds of the carts at those times? earlier time :I cm/s later time :I cm/s (c) What are the locations and times at which the carts pass each other? earlier time S s earlier position S cm later time S 5 later position : cm (d) What is the difference between what is asked in parts (a) and (c) of this problem with regard to the times you found
