Question

s=ut+1/2 at x at
u=10 a=-2 t=1/2
find s

Answer 1

Answer:

-4.7m

Step-by-step explanation: given equation s=ut+1/2at^2

here,

u=10 , a=-2, t=1/2

subistuting the value in the given equation we get,

s=10 x 1/2 + 1/2 x 1/2 x -2 x (1/2)^2

s= 5+1/2 x -1/2

s= 5-1/4

s= -19/4

thus s= -4.7 m
