a 5kg block is pushed along a level surface by a 40N force at an angle of 30 degrees below the surface. The force of friction action on the block is 10N. What is the acceleration of the block? Normal Force? and Coefficient of kinetic friction.

Best ResponseYou've already chosen the best response.0Acceleration F=ma (Rearrange the formula; F uses an angle, and also has a "resistant" frictional force, so remember SOHCAHTOA)

Best ResponseYou've already chosen the best response.0f is force of friction that is being Fx is component of the force applied by you so net force in horizontal direction would be dw:1328602865107:dw solve for than a gives accel;eration
