Alex rode her skateboard to the library. Her velocity changed from 3 m/s west to 1 m/s west in 4 seconds. What was her acceleration?
O A. -2 m/s2 west
O B. -4m/s2 west
OC. 0.5 m/s² west
OD. -3 m/s² west

a = 0.5 m/s²

Explanation:

Given that,

Initial velocity, u = -3 m/s (west)

Final velocity, v = -1 m/s (west)

Time, t = 4 s

We need to find the acceleration of Alex. Acceleration of an object is the rate of change of velocity per unit time. So,

So, her acceleration is 0.5 m/s². Hence, the correct option is (c).

in this scenario it would be the consumer demand as most influential in making the decision. the band members need to figure out where and from whom they will make the most money, in other words who out of the two consumer groups - football fans or car drivers - will spend their money, who is more likely to contribute to their cause and buy what they are offering.
