A car in dynamic equilibrium is acted upon by the following forces: force due to gravity = -9,0000 newtons force to to friction = -250 newtons forward force exerted by engine = 250 newtons what is the value of the force by the ground on the car? -9,000 newtons +9,000 newtons +250 newtons-250 newtons

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
