Explanation:
There are two acceleration acting on the body moving in a circular path
The centripetal acceleration is acting towards the radius is given as
ac=rv2m/s2
ac=40040×40
ac=4m/s2
The tangential acceleration is 3m/s2
The resultant acceleration is32+42
By substituting the values in the above equation we get
We know that the force is given as
F=ma
F=1000×5
Hence the force is 5000N
