Answer in the attachment.

CONCEPT :

• this question is based on law of motion we have provided car of mass 1500 kg curve of radius 250 m at 90 km/hour fist we will multiply
• 90 with 1000 and 60 multiply with 60 we get = 25 m/s then, we will multiply 1500 with 25 and divide with 250 we get = 3750 N

information about force :

• Centripetal force is defined as the force acting on the body moving in a circular path and is directed towards the centre around which the body is moving. Mathematically, centripetal force is given by F = mv²/ r where is the radius of circular path in which the body is moving and m and v are the mass and velocity of that body, respectively.

• Centrifugal Force acts on every object moving in a circular path when viewed from a rotating frame of reference. Some examples of Centrifugal Force are given below. Weight of an object at the poles and on the equator. A bike making a turn. Vehicle driving around a curve.

QUESTION :

• A car of mass 1500 kg rounds a curve of radius 250 m at 90 km/hour. Calculate the centripetal force acting on it.

GIVEN :

• mass = 1500 kg

• radius = 250 m

• velocity = 90 km/hour

TO FIND :

• Calculate the centripetal force acting on it = ?

SOLUTION :

mass m = 1500kg

radius of the curve r = 250m

speed V = 90km/h=90000/3600sec=25m/sec

centripetal force F = mv^2/r

F=1500x(25)^2/250

F=937500/250

F= 3750N

so, force we have = 3750N
