Question

Sahi Ka pH kya hits hai

Answer 1

Given:

a = -9.8 m

t = 2.6 s

vi = 0 m/s

Find:

d = ??

vf = ??

d = vi*t + 0.5*a*t2

d = (0 m/s)*(2.60 s)+ 0.5*(-9.8 m/s2)*(2.60 s)2

d = -33.1 m (- indicates direction)

vf = vi + a*t

vf = 0 + (-9.8 m/s2)*(2.60 s)

vf = -25.5 m/s (- indicates direction
