2. If a bowling ball has a momentum of 72.5 kg m/s and has a speed of 11.2 m/s as it moves down the lane, what is the mass of the ball?

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 many hydrogen (h) atoms are in one molecule of sulfuric acid, h2so4? (1 points) 1 2 4 7

How do we measure or think of speed in the united states?
