Juliette sets the initial velocity to +10 m/s and the acceleration to −2 m/s2, then clicks "start". How can Shakina describe the subsequent motion of the car?

Shakina can sayThe car moves initially to the right with decreasing speed. Eventually, the car stopsand moves to the left with increasing speed.

Explanation:

Because initially the acceleration is negative during which the car is moving to the right and then it slows down and stops, and once it begins moving to the left, it begins to accelerate faster

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?
