Sorry, but i cant see any picture. By the way, u can use conservation of energy for solving this problem..
spring constant 0.5 compression^2 = total K.E. of the two blocks

For the car to stay on the track, the centripetal force must be equal to the centrifugal force.
Hence, the centripetal force = mv2/r = 20001212/30 = 9600 N(its a pseudo force thats directed... link 8 years, 6 months ago
The force exerted by the spring on the mass is 1 kgf.
The spring scale reading shows the tension in the spring, now a tension of 2 kgf, moves a body of 1kg, without acceleration, hence, 1 kgf is... link 8 years, 6 months ago
Weight of the body(W) = 9.8 N
Acceleration due to gravity on Earth(g) = 9.8 m/s2
Hence, mass of the body(m) = 1 kg (W= mg or, m = W/g)
Force exerted on body(F) = 20 N
We know, F= ma
