Apolice car is traveling at a velocity of 18.0 m/s due north, when a car zooms by at a constant velocity of 42.0 m/s due north. after a reaction time of 0.800 s the policeman begins to pursue the speeder with an acceleration of 5.00 m/s2. including the reaction time, how long does it take for the police car to catch up with the speeder?

   t = 10.4 s

Explanation:

given,

velocity of the police car = 18 m/s

reaction time of policeman = 0.8 s

acceleration of the policeman to catch up the speeder = 5 m/s²

time taken to catch the speeder be t₁

distance traveled by the police and the speeder will be same

t₁ = 9.6 s

total time taken by the policeman

     = reaction time + t₁

     = 0.8 + 9.6

     t = 10.4 s

Total time taken by the policeman to catch the speeder is 10.4 s

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

what type of charge does it have? negative
