is the answer 0.366g?

is the answer 1907km?

Answer is 1.96m/s^2?

A cylinder of mass m rests in a supporting carriage. angles either side of cylinder are 45 degrees. the carriage is on an incline of 30 degrees, calculate the maximum acceleration a which the carriage may be given up the incline so that the cylinder does not lose contact at B. right hand side...

will give my answers soon

A 10-kg steel sphere is suspended from a 15-kg frame which slides down a 20 degree incline. the coefficient of kinetic friction between the frame and incline is 0.25, compute the tension in each of the supporting wires A and B (angled 45 degrees from frame), will email picture if wanted

acceleration i used the vectors a and g and used pythagoras to calculate total acceleration 8.55 m/s^2? Also using trigometry on the angle and velocity i calculated a radius of 4290.54m? but using v^2/r the radius is calculated at 2134.51 km? i am clueless on what to do and don't even no what...

So the resultant acceleration is -0.6 m/s2 + 1.87 m/s2 = 1.27m/s2?

thank you for you help, much appreciated.

I used vectors to calculate a and used a = v2/ρ to calculate ρ using v = 4295.1 m/s and a = 8.55 m/s2, multiplying 15450 km/h by 0.278 to convert it to m/s.

All I can calculate is a = -8.55 m/s2 and that ρ = 2157647.25 m, but that doesn't seem right too me as I didn't use the angle or change in orbital velocity (only used final) and also didn't use altitude.

So the final velocity is 10.58 m/s and the acceleration at point B = 1.87 m/s2 ?

actually v2= u2 + 2as ?

acceleration = change in velocity / time and acceleration = velocity2/ radius ?
