. In single particle problem whole mass is concentrated at a single point so it has a single displacement, single velocity and single acceleration. while, in rigid body mass is distributed
Hi There!
Biotic factors are all the living things in an ecosystem, and abiotic factors are all of the non-living things in an ecosystem. So, they differ because they both mean opposite things.
Hope This Helps :)
Answer:
x = -1.20 m
y = -1.12 m
Explanation:
as we know that four masses and their position is given as
5.0 kg (0, 0)
2.9 kg (0, 3.2)
4 kg (2.5, 0)
8.3 kg (x, y)
As we know that the formula of center of gravity is given as




Similarly for y direction we have




Answer:
6667.9 J
Explanation:
We are given that
Mass of cannon.m=14 kg
Time,t=3.15 s
Initial velocity,u=0
We have to find the work done by gravity on the falling cannon ball.


Substitute the values

Work done,W=mgh
Using the formula
