gm A cart moves along the x-axis. Its velocity is given by: ox = 2.27:2 + 5.86t + 2.62 m/s. The cart is at x = 3.92 at t = 0. Give your answer with the correct number of signicant gures, simplify and evaluate all your expressions as much as possible. Part 1) Write an expression for the acceleration of the cart: ax 2 m/s2 Part 2) Write an expression for the displacement of the cart along the x-axis. x 2 It In Part 3) What is the average acceleration of the cart between 2.24 s and 7.45 s? aaVg = i m/s2
