Answer:it's not
Explanation:there's no proof.
Answer:
Velocity between points A and B will be 0.2344 m/s
Answer:
D = 7.82 m
Explanation:
given,
speed of horse = 10 m/s
vertical distance between the saddle and limb = 3 m
horizontal distance = ?
Calculation of time taken to cover the vertical distance.
using equation of motion
initial velocity = 0 m/s
![t = \sqrt{\dfrac{2s}{a}}](https://tex.z-dn.net/?f=%20t%20%3D%20%5Csqrt%7B%5Cdfrac%7B2s%7D%7Ba%7D%7D)
![t = \sqrt{\dfrac{2\times 3}{9.8}}](https://tex.z-dn.net/?f=%20t%20%3D%20%5Csqrt%7B%5Cdfrac%7B2%5Ctimes%203%7D%7B9.8%7D%7D)
t = 0.782 m
horizontal distance covered in this time
D = v t
D = 10 x 0.782
D = 7.82 m
Horizontal distance covered is equal to 7.82 m.
Answer: The highest point upwards and lowest point downward
Explanation:
Amplitude is the point of maximum displacement.
Answer:
4.2 rad/s²
Explanation:
Given:
ω₀ = 3.2π rad/s
ω = 8.8π rad/s
t = 4.2 s
Find: α
ω = αt + ω₀
8.8π rad/s = α (4.2 s) + 3.2π rad/s
α = 4.2 rad/s²
