u Review A compressed spring that is allowed to expand. The weight of a ball that rolls, without slipping, on a flat surface. The frictional force on a crate that is being pushed across a flat floor. Learning Goal: To be able to calculate the work done by a force. If an external force, F, acts on a rigid body, the work, UF, done by the force when it moves along a path s is defined as Up= S, F. dr = S3 F cos 0 dswhere is the angle between the force and the object's direction of motion and ris the position vector that points to the object as it moves along path 8.

The ramp is smooth enough that the friction is negligible Express your answer numerically in meters to three significant figures. Figure 1 of 1 View Available Hint(s) IVO ALOIt vec ?
