If the skater isn't holding on to anything, and there's no friction between the skates and the floor, then there's no way for any force to reach her and make her start moving.
-- No matter what the bus does, the skater stays right where she is.
-- But at the same time, the bus starts moving forward.

Good question
Explanation:
The reason is that walls are made up of more than just atoms. Walls are built up from many things, so with this being said we cannot walk through the walls

It will take 20 seconds for the car to attain a speed of 34 m/s
Explanation:
- Acceleration of an object is given by a = velocity/time.
- Here, acceleration of the car = 1.7 m/s² and velocity = 34 m/s. Using these, find time.
- Time = velocity/acceleration
= 34/1.7 = 20 s
So it takes 20 seconds to attain a speed of 34 m/s
