Answer:
Velocity (v) = 30
Distance = 4km
Acceleration = 0.1ms
Answer:
ACCELERATION = 0.1 ms-2
Explanation:
Given,
u = 10 m/s
v = 30 m/s
s = 4 km = 4000 m
a = ?
The equation of motion :
[tex]v^{2} - u^{2} = 2as[/tex]
900 - 100 = 2 * a * 4000
800 = 8000 a
a = 800 / 8000
a = 1/10 ms-2
a = 0.1 ms-2
Hope it helps !
