. A rock of mass 0.5 kg is launched straight up. A constant upward force of 405 N acted on the rock while it moved 25 cm upward starting from rest. Ignore air resistance. a. Find the launce speed using the work-energy theorem [use g = 10 m/s2). b. Using energy ideas, find the maximum height above the launch point (25 cm) the rock will reach.​

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.
