How does friction make it possible for you to walk across the floor?

if we are walking on a perfectly smooth ground which has no friction our force would simply cancel out the force reverted by the ground and we would fall.

We need it to help push out feet off the ground

Hope those helps :)

Help me, this is my last question pls.

If resultant force on the body is 0 the acceleration will also be 0.​

<h3>What is acceleration?</h3>

The term "acceleration" refers to the change in velocity with time. We must also recall that force is the product of mass and acceleration. If that is so, we can write; F = ma.

Now, we are told that the force on the body is zero so making the acceleration the subject of the formula; a = 0/mand a = 0.

Hence,  if resultant force on the body is 0 the acceleration will also be 0.​

A motorcyclist sees a branch in the road, and hits the brakes, slowing down at -6.42 m/s^2. If it takes him 2.85 s to stop, what
Alex_Xolod [135]

Answer:

his starting velocity was 18.297 ms⁻¹

Explanation:

v = u + at .................. (1)

Where

Final Velocity (v) = 0 ms⁻¹

Initial velocity (u) = ?

Acceleration (deceleration) (a) = -6.42 ms⁻²

time (t) = 2.85 s

Substituting all parameters into equation (1)

0 = u + (-6.42)2.85

0 = u + (-18.297)

0 = u - 18.297

18.297 = u

∴ the initial velocity was 18.297 ms⁻¹
