a car starts from a stopped position at a red light at the end of 30 second its speed is 20 meters per second what is the acceleration of the car
V = a*t
a = V/t = 20/30 = 0.667 m/s^2
DI d
To find the acceleration of the car, we can use the equation:
acceleration = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 0 m/s (car starts from a stopped position)
Final velocity (v) = 20 m/s
Time (t) = 30 seconds
Using the equation for acceleration:
acceleration = (20 m/s - 0 m/s) / 30 s
Simplifying:
acceleration = 20 m/s / 30 s
acceleration = 0.67 m/s²
Therefore, the acceleration of the car is 0.67 m/s².
To find the acceleration of the car, we need to use the formula for acceleration:
acceleration = (final velocity - initial velocity) / time
In this case, the car starts from a stopped position, so its initial velocity is 0 m/s. The final velocity of the car after 30 seconds is 20 m/s. Therefore, the time is 30 seconds, the initial velocity is 0 m/s, and the final velocity is 20 m/s.
Plugging these values into the formula, we get:
acceleration = (20 m/s - 0 m/s) / 30 s
Simplifying, we have:
acceleration = 20 m/s / 30 s
Now, we can divide to find the acceleration:
acceleration = 0.67 m/s²
So, the acceleration of the car is 0.67 meters per second squared.
