Question

Use Newton's 2nd Law to describe why driving at high speeds is dangerous. Use the words force, mass, and acceleration in your answer.

Answer 1

Answer:

According to 2nd Law of Newton:---

A body of mass 'm' moving with a velocity of 'v' has a momentum equal to m×v = ' mv '

Also, The rate of change in momentum is directly proportional to applied force..

Driving at high speed means greater velocity and the mass of the body is always same so we can conclude that driving at high speed is dangerous because of high momentum possessed by the body. If the body collides with another object then it's velocity decreases and acceleration also decreases so The body could experience damage also...

Answer 2

Explanation:

dp/dt=d(mv)/dt

=mdv/dt

=ma =F (force)

if the object of mass 'm' at the velocity of 'v' experience the momentum of 'mv'

then if the 'v' is maximum the force (ma=m×v/t)

is maximum level which act on the objet so it isto very dangerous to handle a object at high speed
