Hi(adsbygoogle = window.adsbygoogle || []).push({});

Could you please help me solve these problems?

A skater with mass m = 80 kg and speed v = 8 m/s hits (colides with ) a spring with spring constant 40 N/m.

a .What is the maximum compression of the spring or in other words , how far will the sping be strecthed?

b. What is the speed of the skater after the spring has been compressed 5 m?

The same spring is now hung vertically from a tower on a bridge such that the free end is at the same level with the road , the skater hangs on to the free end of the spring and jumps over the bridge with an initial velocity v = 0 .

c How far is the spring extended when the skater has attained maximum speed?

d. What energy transfers occur when the skater falls towards the water?

Calculate the following :

1. The skater's maximum speed during the fall

2. How far under the road does the skater stops?

3 The geatest force the skater will experience form the spring during the fall.

Thanks for your help and guidiance in advance.
