Physics 115

[3.14/5 Points] (a) The graph below plots the position versus time for an object moving in one dimension along the x direction. x (m) N t (s) N in What is the speed (magnitude of velocity in m/s) of the object at t = 2.5 s? m/s What direction is the object moving along that time? O +x O -X The object is not moving. What is the acceleration (in m/s2) of the object at t = 2.5 s? (Indicate the direction with the sign of your answer.) m / s 2 Is the speed increasing, decreasing or constant at that time? O increasing O decreasing O constant
