Question

starting from a stationery position, satvik attain a velocity of 20ms-1 in 4 second, while complete for race.calculate his acceleration during a period. assume the acceleration to be uniform.​

Answer 1

Answer: u=0m/s

              v=20m/s

               t=4s

               a=?

v=u+at

20=0+a*4

20=4a

a=20/4

=5m/s^2

Answer 2

$\huge {\boxed {\boxed{\mathfrak{\red {Solution}}}}}$

u=0

v=20 m/s

t=4 secs

a=?

$\underline\orange{Using\:First\:Equation\:Of\:Motion}$

》v=u+at

》20=0+a(4)

》20=4a

》a=20/4

${\boxed{Acceleration=5\:ms^2}}$
