This drag force is always opposite to the object's motion, and unlike friction between solid surfaces, the drag force increases as the object moves faster.
Answer:
70 revolutions
Explanation:
We can start by the time it takes for the driver to come from 22.8m/s to full rest:
The tire angular velocity before stopping is:
Also its angular decceleration:
Using the following equation motion we can findout the angle it makes during the deceleration:
where 
= 0 m/s is the final angular velocity of the car when it stops, 
= 114rad/s is the initial angular velocity of the car 
= 14.75 rad/s2 is the deceleration of the can, and 
is the angular distance traveled, which we care looking for:
or 440/2π = 70 revelutions
Answer:
because the mass of the apple is very less compared to the mass of earth. Due to less mass the apple cannot produce noticable acceleration in the earth but the earth which has more mass produces noticable acceleration in the apple. thus we can see apple falling on towards the earth but we cannot see earth moving towards the apple.
Hi There! :)
