Acceleration = change in velocity/time
= 40/5
=8m/s^2
IM sure there is C, D, and E in kuiper belts, but not really sure of silicon and iron
Is potential energy that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system
I cant do all but I can do number 4
When force moves ur leg u start skatin and when that happenes ur using a lot of force to move
Answer:
The speed of the block is 4.96 m/s.
Explanation:
Given that.
Mass of block = 1.00 kg
Spring constant = 500 N/m
Position 
Coefficient of friction = 0.350
(A). We need to calculate the speed the block has as it passes through equilibrium if the horizontal surface is friction less
Using formula of kinetic energy and potential energy

Put the value into the formula




Hence, The speed of the block is 4.96 m/s.
