12. Energy from the breaking of atomic bonds in molecules (ex: C4 explosion) does anybody know this

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

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?
