An object is moving along the x-axis and its position varies in time according to the expression x = (5.00 m/s2)t2, where x is in meters and t is in seconds. (a) determine its position (in m) at t = 2.40 s.

28.8 m

Explanation:

According to the question, the position of the body changes with time according to the equation given as

(a) The position of the object at t = 2.4 s

Substitute the value of t as 2.4 s in the above expression, we get

x = 28.8 m

Thus, the position of the object at t = 2.4 s is 28.8 m.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
