Question
A car of mass 1400 kg drives in a circle of radius 50 m. If the car has a speed of 10 m/s, what is the centripetal force acting on the car?A.1400 NB.280 NC.2800 ND.140 N
Solution
The centripetal force can be calculated using the formula:
F = m * v^2 / r
where: F is the centripetal force, m is the mass of the object (in this case, the car), v is the speed of the object, and r is the radius of the circle.
Plugging in the given values:
F = 1400 kg * (10 m/s)^2 / 50 m
Solving this gives:
F = 1400 kg * 100 m^2/s^2 / 50 m
F = 2800 N
So, the correct answer is C.2800 N.
