At which point will the riders experience centripetal acceleration?
1 answer:
As we know that centripetal acceleration is given as
so here we all know that radius of curvature of straight surface or flat surface is infinite or very large
So here acceleration will be zero when it move on flat surface
So here at points "w" , "x" , "z" the surface will be flat surface
and hence the observer will not experience centripetal acceleration
while at point Y the surface is curved and hence the observer will experience centripetal acceleration

Answer:
The front of the black car
Explanation:
The position -21 is shown on the diagram at the front of the white van. The reference point is the position 0, which is shown on the diagram as the front of the black car.
Hi!
The energy of the block is 4 m/s
To calculate this, you need to use the equation for kinetic energy. The block is sliding (i.e. it's moving). If the object is sliding across a level surface, the only energy it has is kinetic energy, because there is no change in potential energy (which changes with height). So, the mechanical energy will be pure kinetic energy. The equation is the following, derived from the expression for kinetic energy:
