A car of mass 1200kg is moving on a road at the speed of 60km/hr.if coefficient of friction is 38, and Normal force is 50N. The frictional force acting on the car is given by
To find the frictional force acting on the car, we can make use of the formula:
frictional force = coefficient of friction * normal force
Given:
Mass of the car (m) = 1200 kg
Speed of the car (v) = 60 km/hr
Coefficient of friction (μ) = 0.38
Normal force (N) = 50 N
First, let's convert the speed from km/hr to m/s:
Speed in m/s = (60 km/hr) * (1000 m/km) * (1 hr/3600 s)
Speed in m/s = 16.67 m/s (approximately)
Next, we can calculate the frictional force using the formula:
frictional force = coefficient of friction * normal force
frictional force = (0.38) * (50 N)
frictional force = 19 N
Therefore, the frictional force acting on the car is 19 N.
The frictional force acting on the car can be calculated using the formula:
Frictional force = coefficient of friction * Normal force
Given:
Mass of the car (m) = 1200 kg
Speed of the car (v) = 60 km/hr (which needs to be converted to m/s for calculations)
Coefficient of friction (μ) = 0.38
Normal force (N) = 50 N
To convert the speed from km/hr to m/s, we divide it by 3.6:
Speed in m/s = 60 km/hr ÷ 3.6 = 16.67 m/s
Now we can substitute the values into the formula:
Frictional force = μ * N
Frictional force = 0.38 * 50 N
Frictional force = 19 N
Therefore, the frictional force acting on the car is 19 Newtons.
