Answer:
Displacement in next 4 sec = 15 m
Explanation:
u = 5 m/s
a = -2.5 m/
t = 4 sec
s = 5*4 - 0.5*2.5*4
s = 20 - 1.25*4
s = 20 - 5
s = 15 m

- Initial velocity (u) = 5m/s
- acceleration (a) = -2.5m/s²
- Displacement in next 4 seconds!= ?
Using 2nd equation of equation,
Here
S = displacement
u = initial velocity
t = time taken
a = acceleration
Now put the Given values..
