Distance travelled by a free falling object in the first second is: a) 4.9m b) 9.8m c) 19.6m d) 10m​

Sagot :

  • Time=1s=t
  • Acceleration due to gravity=g=9.8m/s^2
  • Distance=s

In free fall

[tex]\boxed{\sf s=-\dfrac{1}{2}gt^2}[/tex]

[tex]\\ \sf\longmapsto s=-\dfrac{1}{2}\times 9.8(1)^2[/tex]

[tex]\\ \sf\longmapsto s=-4.9(1)[/tex]

[tex]\\ \sf\longmapsto s=-4.9m[/tex]

  • Take it positive

[tex]\\ \sf\longmapsto s=4.9m[/tex]

  • Option a is correct
