Answer:
A
Explanation:
60 + 30 = 90
90 divided by 3 = 30
30 divided by 60 = 0.5
so your answer is 0.5 m/s
Answer:
300x480 teaspoons
Explanation:
when converting cups to teaspoons just multiply by 48
Answer:
avriage force F = 2722.5 N
Explanation:
For this problem we can use Newton's second law, to calculate the average force and acceleration we can find it by kinematics.
vf² = v₀² - 2 ax
The final carriage speed is zero (vf = 0)
0 = v₀² - 2ax
a = v₀² / 2x
a = 1.1²/(2 0.200)
a = 3.025 m / s²
a = 3.0 m/s²
We calculate the average force
F = ma
F = 900 3,025
F = 2722.5 N
Gravity is also called gravitation
