A stone is thrown vertically upwards with an initial velocity of 40m/s.Find the maximum height reached by the stone. What is the netdisplacement and total distance covered by the stone?VERY URGENT PLS ANSWER GR 9 QUESTION

Answer»

Answer:

81.63 meters

Explanation:

We will USE the following equation

{v}^{2}  -  {u}^{2}  = 2as

initial \: <klux>VELOCITY</klux> \:  = 40m {sec}^{ - 1}

At MAX height,final velocity is ZERO

{0}^{2}  -  {40}^{2}  = 2 \times ( - 9.8) \times s

(Negative Acceleration)

Solving,

s =  \frac{1600}{19.6}

s = 81.63m

Total distance is 163.26 m

Total displacement is zero
