A projectile is shot horizontally at 59.9 m/s from the roof of a building 67.0 m tall. Determine the time necessary for the projectile to reach the ground below. Determine the distance from the base of the building that the projectile lands. Determine the horizontal and vertical components of the velocity just before the projectile reach the ground.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
