Force is defined as mass times acceleration. Starting with SI base units, derive a unit for force. Using SI prefixes suggest a convenient unit for the force resulting from a collision with a 10-ton trailer truck moving at 55 miles per hour. (Assume 1 second deceleration time)

Answer :

Answer:

S.I unit of force is N

Therefore the resulting force = 245872 N

Explanation:

F = m × a

   [tex]=\frac{m \times v}{t}[/tex]

   [tex]= \frac{Kg\times \frac{m}{s} }{s}[/tex]

  [tex]=\frac{Kg \times m}{s^2}[/tex]

   =N

S.I unit of force is N

10 ton =10000 kg  ,  55 miles =88.5139 km  and 1 hour = 3600 s

55 mile per hour= 0.0245872 km/s=24.5872 m/s

Here m= 10000 kg,  v= 24.5872 m/s   and t= 1 s

[tex]F=\frac{10000\times 24.5872}{1} N[/tex] = 245872 N

Therefore the resulting force = 245872 N
