Under maritime law, cruise ships are not allowed to discharge their garbage at sea. t or f

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) determine the magnitude and direction of projectile velocity at t= 1.3s b) determine the magnitude and direction of projectile acceleration at t=1.3s

How are calculation for velocity and speed different

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds
