Calculate the momentum of 2500 kg truck: A. moving at 18m/s B. parked in a driveway

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
