Answer:
(a). The blood travel during this acceleration is 0.0231 m.
(b). The time for the blood to reach its peak speed is 0.0459 sec.
Explanation:
Given that,
Acceleration = 22.0 m/s²
Speed = 1.01 m/s
(a). We need to calculate the distance
Using equation of motion
Where, v = final speed
u = initial speed
a = acceleration
s = distance
Put the value into the formula
(b). We need to calculate the time
Using equation of motion
Put the value into the formula
Hence, (a). The blood travel during this acceleration is 0.0231 m.
(b). The time for the blood to reach its peak speed is 0.0459 sec.
Newton's 3rd law of motion says that for every action there is an equal and opposite reaction.
This means that the smaller mass exerts a force on the larger mass that is equal in magnitude and opposite in direction to the force that the larger mass exerts on the smaller mass.
Choice 2
Answer:
i dont know this but please answer before tomarrow please
Explanation:
thanks
Because there is no gravity and sound moves through gravity
Answer:
Change in velocity: 88 m/s
Average velocity: 50 m/s
initial velocity: 5.9 m/s
Final velocity: 94 m/s
Initial momentum: 3.6 kg m/s
Final momentum: 58 kg m/s
Explanation:
Acceleration = change in velocity / time
9.8 m/s² = Δv / 9.0 s
Δv = 88 m/s
Work = change in energy
Fd = ΔE
(6.0 N) d = 2700 J
d = 450 m
Average velocity = distance / time
v_avg = 450 m / 9.0 s
v_avg = 50 m/s
v − v₀ = 88 m/s
½ (v + v₀) = 50 m/s
Solving the system of equations:
v + v₀ = 100 m/s
2v = 188 m/s
v = 94 m/s
v₀ = 5.9 m/s
Use Newton's second law to find the mass:
F = ma
6.0 N = m (9.8 m/s²)
m = 0.61 kg
Find the momentums:
p₀ = (0.61 kg) (5.9 m/s) = 3.6 kg m/s
p = (0.61 kg) (94 m/s) = 58 kg m/s
