A racing car of mass 850 kg accelerates from 16.0 m/s [N] to 48.0 m/s [N] in 8.0 s. Find the net force acting on the racing car.
force= mass* acceleration= 850(48-16)/8.0= ....
Well, well, well, we're talking about racing cars now! Vroom vroom! Let's calculate the net force acting on this speedy machine, shall we?
To find the net force, we're going to use Newton's second law, which states that force is equal to mass multiplied by acceleration.
So, let's get down to business. The mass of the car is given as 850 kg, and the time taken is 8.0 s. We're given the initial velocity (16.0 m/s [N]) and the final velocity (48.0 m/s [N]).
First, let's calculate the acceleration. We can use the formula:
acceleration = (final velocity - initial velocity) / time
Substituting the given values into the formula:
acceleration = (48.0 m/s [N] - 16.0 m/s [N]) / 8.0 s = 4.0 m/s²
Now that we have the acceleration, we can find the net force:
force = mass * acceleration = 850 kg * 4.0 m/s²
Calculating that, gives us:
force = 3400 N
So, the net force acting on the racing car is 3400 Newtons. Keep those wheels spinning! 🚗💨
To find the net force acting on the racing car, we can use Newton's Second Law of Motion, which states that the net force (F net) acting on an object is equal to its mass (m) multiplied by its acceleration (a):
F net = m * a
Given:
Mass of the racing car (m) = 850 kg
Initial velocity (u) = 16.0 m/s [N]
Final velocity (v) = 48.0 m/s [N]
Time taken (t) = 8.0 s
First, we need to calculate the acceleration (a) using the formula:
a = (v - u) / t
Here, u = 16.0 m/s [N], v = 48.0 m/s [N], and t = 8.0 s:
a = (48.0 m/s - 16.0 m/s) / 8.0 s
a = 32.0 m/s / 8.0 s
a = 4.0 m/s^2
Now, we can calculate the net force (F net):
F net = m * a
F net = 850 kg * 4.0 m/s^2
F net = 3400 N
Therefore, the net force acting on the racing car is 3400 Newtons.
To find the net force acting on the racing car, we can use Newton's second law of motion, which states that the net force applied to an object is equal to the product of its mass and its acceleration.
The mass of the racing car is given as 850 kg, and the change in velocity is from 16.0 m/s [N] to 48.0 m/s [N] over a time interval of 8.0 s.
First, we need to find the acceleration of the racing car. We can use the equation:
acceleration = (final velocity - initial velocity) / time
acceleration = (48.0 m/s - 16.0 m/s) / 8.0 s
acceleration = 32.0 m/s / 8.0 s
acceleration = 4.0 m/s^2
Now that we have the acceleration, we can calculate the net force using the formula:
net force = mass * acceleration
net force = 850 kg * 4.0 m/s^2
net force = 3400 N
Therefore, the net force acting on the racing car is 3400 Newtons (N).
