A car of mass 1200kg increases its velocity from 20m/s to 60m/s in 8seconds. Calculate the acceleration force on the car.
A car of mass 1200kg is accelerated from rest to a velocity of 20m/s , Calculate the work done by the engine force
To calculate the acceleration force on the car, we can use Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration (F = m * a).
Given:
Mass of the car (m) = 1200 kg
Initial velocity (u) = 20 m/s
Final velocity (v) = 60 m/s
Time (t) = 8 seconds
The acceleration (a) can be calculated using the formula:
a = (v - u) / t
Let's calculate the acceleration first:
a = (60 m/s - 20 m/s) / 8 s
a = 40 m/s / 8 s
a = 5 m/s²
Now, we can calculate the acceleration force (F) using the formula:
F = m * a
F = 1200 kg * 5 m/s²
F = 6000 N
Therefore, the acceleration force on the car is 6000 N.
To calculate the acceleration force on a car, we need to use Newton's second law of motion, which states:
Force (F) = mass (m) * acceleration (a)
First, let's calculate the acceleration (a):
Acceleration (a) = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 20 m/s
Final velocity (v) = 60 m/s
Time (t) = 8 s
Acceleration (a) = (60 - 20) / 8
Acceleration (a) = 40 / 8
Acceleration (a) = 5 m/s^2
Now that we have the acceleration (a), we can calculate the force (F):
Force (F) = mass (m) * acceleration (a)
Given:
Mass (m) = 1200 kg
Acceleration (a) = 5 m/s^2
Force (F) = 1200 kg * 5 m/s^2
Force (F) = 6000 N
Therefore, the acceleration force on the car is 6000 Newtons (N).
