An engine is attahed to a wagon through a shock absorber of length 1.5m. The system with a total mass of 50,000kg is moving with a speed of `36kmh^(-1)` when the brakes are applied to bring it to rest. In the process of the system being brought to rest, the spring of the shock absorber gets compressed by `1.0m`. If `90%` of energy of the wagon is lost due to friction, calculate the spring constant.

An engine is attached to a wagon through a shock absorber of length 1.5 m. The system with a total mass of 50,000 kg is moving with a speed of 36 km h^-1 when the brakes are applied to bring it to rest. In the proces of the system being brought to rest, the spring of the shock absorber gets compressed by 1.0 m. If 90% of energy of te wagon is lost due to friction. calculate the spring constant.

An engine is attached to a wagon through a shock absorber of length 1.5 m. The system with a total mass of 40,000 kg is moving with a speed of 72 kmh^(1) when the brakes tare applied to bring it to rest. In the process of the system being brought to rest, the spring of the shock absorber gets compressed by 1.0 m. If 90% of energy of the wagon is lost due to friction, the spring constant is ________ xx 10^5 N/m.

An engine is attached to a wagon through a shock absorber of length 1.5 m . The system with a total mass of 50,000 kg is moving with a speed of 36 ^kmh(-1) when the brakes are applied to bring it to rest, the spring of the shock absorber gets compressed by 1.0 m. If 90 % of energy of the wagon is lost due to friction, calculate the spring constant.

A train wagon is attached to the engine through a shock absorber 1.5 m long the system having a total mass of 5 x 104 kg is going at a speed of 36 km/h. Suddenly the brakes are applied to bring them to rest. In the process of coming to rest, the spring of the shock absorber gets compressed by 1 metre. If only 90% energy of the wagon is lost due to friction. What is spring constant of spring?

A motorcycle is being driven at a speed of 20 m/s when brakes are applied to bring it to rest in five seconds. The deacceleration produced in this case will be :
