Answer:
A mass of 4 Kg rest on the horizontal plane. The plane is gradually inclined until at an angle of θ=15
∘
with the horizontal,the mass just being to slide what is the coffeficient of static friction between the block & the surface.
Explanation:
Answer:
As much I know the gravity on moon is 1.62m/s२.
They were going at a velocity 4.07m/s
<u>Explanation:</u>
Distance s =5 m
initial velocity u= 0.8 m/s
Acceleration a =1.6m/s2
We have to calculate the velocity with which they were going afterwards i.e final velocity.
Use the equation of motion
![v^2=u^2+2as\\=0.8^2+2\times 1.6\times 5\\=16.64\\v=4.07 m/s](https://tex.z-dn.net/?f=v%5E2%3Du%5E2%2B2as%5C%5C%3D0.8%5E2%2B2%5Ctimes%201.6%5Ctimes%205%5C%5C%3D16.64%5C%5Cv%3D4.07%20m%2Fs)
They were going with a velocity 4.07 m/s afterwards.
