Answer:
Explanation:
From the question we are told that
Mass of block
Radius of circle
Force of track
Normal Force on block
Generally the equation for Velocity of block is mathematically Given by the law of conservation of energy
For initial velocity
0.660 = 0.0425 x u^2/0.525 - 0.0425 x 9.8
Generally the equation for work done is mathematically Given by
<span>You should increase the distance between your car and the vehicle ahead when you are being tailgated by another driver.
Tailgated is a condition when the vehicle behind you is very close to you that there is no distance between your vehicle and the vehicle behind you. In that case you should increase distance from the vehicle ahead to avoid collision in any case. These days people were mostly in hurry and everyone want to go ahead, so tailgating is very common.</span>
