Answer:
This slide shows the three forces that act on a baseball in flight. The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion
Work = (force) x (distance)
The work he did: Work = (700 N) x (4m) = 2,800 joules
The rate at which
he did it (power): Work/time = 2,800 joules/2 sec
= 1,400 joules/sec
= 1,400 watts
= 1.877... horsepower (rounded)
When minerals are exposed to high pressure and temperatures, the individual minerals begin to realign themselves
Mass, m = 85 kg, velocity = 15 m/s, radius = 20m.
Centripetal force = mv²/r
F = 85*15²/20 = 85*15*15/20 = 956.25 N
A compound is elements bonding together, an element is the pure substance
