Question

solved this by using the following forluma
${s = ut + \frac{1}{2} a } {t}^{2}$

u=7, t=4, s=92, a =?

​

Answer 1

Answer:

hey here is your answer

pls mark it as brainliest

Step-by-step explanation:

so basically

s=ut+1/2at square is Newton's second law of motion

so here u=7

t=4

s=92

substituting these values in given equation

we get

92=(7×4)+1/2×a×4×4

ie 92=28+2a×4

ie 8a=64

so a=8 m/s square

so value of acceleration due to gravity ie value of a is 8 m/s square here
