Answer:
Golfer B hits his golf ball at a higher rate of speed and with more force. This means that golfer B's ball will travel for a longer period of time and a longer distance due to newtons first law, where it says an object in motion stays in motion, with the same speed and in the same direction.
Explanation:
Answer:
A picture of a baseball being thrown tworad a batter at home plate.
Bulbs c and b would still be screwed in if they were in to begin with and bulbs A, D, and E. would be unscrewed
It could increase homocysteine levels—and when these levels are raised, it could make the inner linings of the arteries to be damage and it usually occurs because of unwanted clotting increasing in a person’s body of which could cause factor or contributors making the increase, such as like smoking—this increases, the unwanted blood clots in the body which makes these levels increase, producing unwanted defects.
given that :
UA=15i+30j and UB =-10+5.0j
speed before collision is given as
u₁ = sqrt(15² + 30²) = 33.5 m/s
and
u₂ = sqrt((- 10)² + 5²) = 11.2 m/s
total kinetic energy before collision is given as
KE = (0.5) m u²₁ + (0.5) m u²₂ = (0.5) (2) (33.5)² + (0.5) (2) (11.2)² = 1247.7 J
similarly final speed after collision is given as
v₁ = sqrt((- 5)² + (20)²) = 20.6 m/s
v₂ = sqrt((10)² + (15)²) = 18 m/s
total kinetic energy after collision is given as
KE' = (0.5) m v²₁ + (0.5) m v²₂ = (0.5) (2) (20.6)² + (0.5) (2) (18)² = 748.4 J
Change in kinetic energy is given as
ΔKE = KE' - KE
inserting the values
ΔKE = 748.4 - 1247.7
ΔKE = - 499.3 J
hence kinetic energy lost comes out to be 499.3 J
