Two horizontal forces are exerted on a large crate. the first force is 317 n to the right. the second force is 173 n to the left a. draw a force diagram for the horizontal forces acting on the crate. b. what is the net force acting on the crate? c. the box is initially at rest. five seconds later, its velocity is 6.5 m/s to the right. what is the crate's mass?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
