30.50 km/h 30.50^3 m / 3600s 8.47 m/s At the top of the circle the centripetal force (mv?/R) comes from the car's weight (mg) So, the net downward force from the car (Fn) (weight - centripetal force) .. and by reaction this is the upward force provided by the road .. Fn mg - mv?/R Fn m(g - v?/R) .. .. 1800kg (9.80 - 8.47?/20.20) .. .. .. ?Fn 11 247 N (upwards) (b) When the car's speed is such that all the weight is needed for the centripetal force .. then the net downward force (Fn), and the reaction from the road, becomes zero. ie .. mg mv?/R .. .. v? Rg .. .. 20.20m x 9.80 198.0(m/s)? ?v √198 14.0 m/s
You have the right to fire him but you need to see what the conditions of the contract were. When you hired him, I'm sure you signed a contract that outlined everything. It should have told you how much he charges for filing stuff, for communicatint to you or anyone else regarding the case, etc. You need to take a look at that to see how much you owe him or how much he needs to refund you. Hopefully you didn's sign a contract that says your retainer fee is non-refundable. At any rate, just look at your contract you signed when you retained him and that will give you an idea of what to do next.
