solve the problem a = ? a = v/t solve t using d=.5(v-V)t t= 8.8sec sub in the equation a = (27m/s)/8.8sec a = 3.06m/s^2 F= mass*acceleration 810kg*3.06m/s^2 = 2485N = 2500N

Homework Statement a 50kg block of wood is pressed against a smooth wall by a force perpendicular to the wall. if the coefficient of static function is .13, what is the minimum force that is necessary to keep the block of wood in place. Homework Equations Fg= mg Fn = ma Ff= µ Fn = µma...

Homework Statement a block is accelerating 2.31m/sec^2 horizontally. the block is .2485Kg. what is the coefficient of the kinetic force and the kinetic force? Homework Equations Normal force = weight = mg Fk= kinetic friction coefficient (µkinetic) / normal force (Fnormal) kinetic...

Thanks a lot for trying to solve that problem. the problem is solved by the help of my teacher. I appreciate your help.

Homework Statement A constant acceleration forces "Force(a)" pushes a 2.kg FedEX package across a frictionless floor on which an xy coordinate system has been drawn. the figure below gives the packag's x and y velocity components versus time. What are the (a) magnitude and (b) the direction of...
