Due to friction with the earth's atmosphere, a large static electric charge could build up on a plummeting asteroid fragment. would you expect the fragment to generate a electric field in this situation? explain why or why not.

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s

Acar moves a distance of 50.0 km west, followed by a distance of 64.9 km north what was the magnitude of the displacement of the car, in units of kilometers?

Each line (unit) on the horizontal axis represents: 5 years 10 years 20 years all of the above
