Answer:
The acceleration is: a = -2 m/s²
The negative sign indicates that velocity is decreasing with time.
Step-by-step explanation:
Given
- Initial velocity u = 10 m/s
To determine
Acceleration a = ?
Using the formula to determine the acceleration
a = (v - u) / t
substituting u = 10 m/s, v = 0 and t = 5
a = (0 - 10) / 5
a = -10 / 5
a = -2 m/s²
Thus,
The acceleration is: a = -2 m/s²
The negative sign indicates that velocity is decreasing with time.
4x5-(2 (2) - 2 ) = 14
(18/ 3) + (3 (2) - 7) 8
Answer:
D: x=12
Step-by-step explanation:
To calculate the speed, divide 15.75 by 2.25 and you get 7 mph.
