Question

a stone dropped from a window reaches the ground in 0.5 second given acceleration equals to 10ms-2
1. calculate the speed just before it hits the ground
2. what is the average speed at time equals to 0.5 second
3. calculate the height of Window from the ground ​

Answer 1

Answer:

a=10ms^2

t=0.5seconds

u=0m/s

thus,

Explanation:

according to first equation of motion,

v=u+at

or, v= 0+10*0.5

or, v=5m/s

hope it helps u

Answer 2

Answer:

1 .5m/s

2.20m/s

3.1.25
