Red blood cells contain hermoglobin whiles white blood cells do not. Hermoglobin is what gives it its red color.
The ship's average speed during the 12 seconds is
(1/2) (58 + 153)
= (1/2) (211 m/s)
= 105.5 m/s .
Traveling for 12 seconds at an average speed of 105.5 m/s ,
the ship covers
(12 sec) x (105.5 m/s)
= 1,266 meters during the acceleration

Answer:
The average force the golf club exerts on the ball is 600 N
Explanation:
Newton's second law of motion states that force, F, is directly proportional to the rate of change of momentum produced
F = m× (v₂ - v₁)/(Δt)
The given parameters of the motion of the ball are;
The mass of the ball, m = 45 g = 0.045 kg
The initial velocity of the ball, v₁ = 0 m/s
The speed with which the ball was hit by the golfer, v₂ = 40 m/s
The duration of contact between the golf club and the ball, Δt = 3 ms = 0.003 seconds (s)
By Newton's law of motion, the average force, 'F', which the golf club exerts on the ball is therefore, given as follows;
F = 0.045 kg × (40 m/s - 0 m/s)/(0.003 s) = 600 N
The average force the golf club exerts on the ball = F = 600 N.
