can someone please help to reason out this. because i am confused...is the question about static friction..please help
On a truck which is moving straightforward on an horizontal road there is a big cube of concrete of mass m. The mass of the truck is M. The truck brakes suddenly with an acceleration of modulus a. Find: a) the maximum allowed acceleration amax in order that the concrete doesn’t slide on the truck;
b) the dynamical friction force acting on the truck if a =2 amax .
Data: m = 500 [kg;] M = 10000 [kg]
