At time t = 0 an object is traveling to the right along the axis at a speed of 10 m/s with acceleration -2.0 m/s2. Which statement is true?
a. The object cannot have a negative acceleration and be moving to the right.
b. The object will continue to move to the right, slowing down but never coming to a complete stop.
c. The object will slow down, momentarily stopping, then pick up speed moving to the left.
d. The object will slow down, eventually coming to a complete stop.

Respuesta :

Answer:

C. The object will slow down, momentarily stopping, then pick up speed moving to the left.

Explanation:

Given that

Speed of the object = 10 m/s ( right direction)

Acceleration ,a=  - 2 m/s

A negative sign shows that acceleration is in the opposite direction to the speed.

We know that if speed and acceleration is in the opposite direction then the final speed of the objects becomes zero. for a moment and it will increase in the opposite direction.

Therefore the answer is C
