A car slows down from +32 m/s to +8 m/s in 4s. Calculate the acceleration .
a = change in velocity / change in time
so..
a = 8 - 32 / 4
a = -6m/s^2
Carl puts the pedal to the metal and increases her speed as follows: 0 mi/hr at 0 seconds; 10 mi/hr at 1 second; 20 mi/hr at 2 seconds; 30 mi/hr at 3 seconds; and 40 mi/hr at 4 seconds. What is the acceleration of Car;'s car?
Friction force acting on the box if a horizontal force is applied with a magnitude of 0 N
What is the term used to describe a force that equals the sum of two or more forces?
a soccer ball is kicked with a velocity of 8m/s at angle of 23°. what is the ball's acceleration in the vertical directions as it flies through the air
To calculate the acceleration, we need to use the formula:
acceleration = change in velocity / time
In this case, the change in velocity is given as -32 m/s (since the car is slowing down) and the time is 4 seconds. However, we first need to find the magnitude of the change in velocity by subtracting the initial velocity from the final velocity.
Magnitude of change in velocity = |final velocity - initial velocity|
= |8 m/s - 32 m/s|
= |-24 m/s|
= 24 m/s
Now we have the magnitude of the change in velocity and the time, we can calculate the acceleration:
acceleration = change in velocity / time
= 24 m/s / 4 s
= 6 m/s²
Therefore, the acceleration of the car is 6 m/s².
