But how can the only number that is less than 4 or equal to 4 be 8
​

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

An object's buoyant force and weight mean the same thing. a. trueb. false

If anyone who can me with this hw? i would really appreciate it
