Answer:
By using the first equation of motion:
V =u +at
Here initial velocity is zero "0"
Put the values.
V = 0 + gt (since g = 9.8 m/s2)
V = gt = 9.8 x 2.6
= 25.48 m/s
Now find the distance by using the 2nd equation of motion.
S = ut+(1/2)at2 (Since u = o)
S = (1/2)gt2
S= (1/2) x 9.8 x (2.6)2
S= 9.8 x 6.76 /2
S = 66.248 / 2
S= 33. 124 m
