Nate the skate was an avid physics student whose main non‑physics interest in life was high‑speed skateboarding. in particular, nate would often don a protective suit of bounce-tex, which he invented, and after working up a high speed on his skateboard, would collide with some object. in this way, he got a gut feel for the physical properties of collisions and succeeded in combining his two passions\.\* on one occasion, the skate, with a mass of 123 kg, including his armor, hurled himself against a 825 kg stationary statue of isaac newton in a perfectly elastic linear collision. as a result, isaac started moving at 1.43 m/s and nate bounced backward. what were nate's speeds immediately before and after the collision? (enter positive numbers). ignore friction with the ground. speed before: m/s speed after: m/s

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
