A truck, moving at 30 m/s , speeds up at a rate of 10 m/s ^ 2 over a distance of 80 m What the truck's tinal velocity be ?

pe = weightxheight = 2000x1000=2,000,000joules

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

explanation:

-reverse card

its a 5.5 n

glad that

the answer is 12 as i may remember
