Question

question 1
A railroad flatcar is loaded with crates. The coefficient ofstatic friction between the crates and the floor is 0.21. If thetrain is moving at 44.6 km/hr, in how short adistance can the train be stopped with a constant accelerationwithout causing the crates to slide? question 2 A block is at rest on an inclined plane whoseelevation can be varied. The coefficient of static friction isms= 0.42, and thecoefficient of kinetic friction is mk = 0.16. The angle ofelevation q is increased slowly from thehorizontal. At what value of q does theblock begin to slide (in degrees)?

What is the acceleration of the block?
