Two objects, each of mass 2 kg, are moving in the same straight line but in opposite directions. They are moving with velocities 10 m/s and 5 m/s respectively before the collision during which they stick together. The velocity of the combined object after collision is,

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

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.

Hunter’s velocity was 4.5 m/s. at the end of his race, his velocity was the same. which best describes his movement? his movement stopped. his acceleration is zero. his time was constant. his acceleration was positive.
