Question

2 u = 16 m/s
t-5s
s=105m
a= ?​

Answer 1

Answer:

2 m/s^2

Explanation:

S=ut +1/2at^2

105=16*5+1/2*a*5*5

105-80 =25/2*a

25*2/25 =a

a=2m/s^2

Answer 2

Answer:

u=16/2 = 8m/s

t= 5s

s= 105m

Using position time relation,:-

s = ut + 1/2at²

105 = 8×5 + 1/2a(5)²

105 = 40 + 25/2a

105-40 = 25/2a

25/2a = 65

a = 65×2/25

a = 5.2m/s²

Hope it helps you!
