Physics

A frictionless cart of mass ? = 4.00 kg has a shape of a rampwith an incline angle ? = 60.0Â°. The ramp is pulled by a constanthorizontal force ? = 15.0 N. Another frictionless cart of mass? =2.00 kg can roll along the ramp and is attached to the top of theramp at point ? by a spring of constant ? = 300. N/m. The spring isfree to pivot without friction around point ?. Assume that themotion of the carts has stabilized, i.e. the top cart ? doesnâ€™toscillate with respectto ramp and the spring maintains a constantamount of stretch. Find acceleration of the carts, normal forcebetween the carts and the amount of stretch of the spring.
Please can you do it step by step, so i can understand what isgoing on ?
