Explanation:
area=length(m) ×breadth(m) . The unit of area is expressed in terms of fundamental units m^2.thus it is derived unit
¡Hellow!
For this problem, lets recabe information:
v (Velocity) = 10 m/s
a (Aceleration) = 1 m/s²
t (Time) = 1/4 min = 25 s
d (Distance) = ?
v' (Final velocity) = ?
First, for calculate distance, lets applicate formula:

Lets replace according we information and let's resolve it:
d = 10 m/s * 25 s + (1 m/s² * (25 s)²) * 0,5
d = 250 m + (625 m) * 0,5
d = 2,5 m + 312,5 m
d = 314 meters.
Now, for calculate final speed, lets applicate formula:

Lets replace according we information and let's resolve it:
v' = 10 m/s + 1 m/s² * 25 s
v' = 10 m/s + 25 m/s
v' = 35 m/s
¿Good Luck?

Answer:
Acceleration occurs when an object changes its VELOCITY or DIRECTION or both.
Explanation:
Answer:
-7 m
Explanation:
Displacement is a vector connecting the initial position of motion of an object to its final position.
For the car in this problem, we have:
- Initial position: + 11 m
- Final position: + 4 m
Therefore, the vector displacement will be:
d = +4 - (+11) = -7 m
Which means:
- Magnitude of 7 m
- Negative direction
Answer:
C
Explanation:
When an object has a greater mass than the drag force pushing it back then it is moving forward therefore making car C faster than car D. If car D was much smaller it wouldn't have enough mass to push past the drag force.
