Question

Take the uniform accelartion near the surface of earth to be 9.8 ms 2 for a free fall. What is
the velocity of a body at the end of two second of free fall, if the initial velocity is zero?
(8=9.8m/s²)

please​

Answer 1

a = 9.8 m/s square

u = 0 m/s

t = 2 sec

v = ?

as we already know......

v = u + at

=> v = 0 + (9.8 × 2)

=> v = 19.6 m/s

hope it's helpful.....!!
