Question

Acceleration
Distance travelled s = 14+02
200+ 5x5x4
80+ 40 = 120 m
A car came to rest when brake was applied for us to get a retardation
of 3 m/s. Calculate how far the car would have travelled after applying
the brake.
a = -3 m/s
t = 45
v=0
v=u + at
-u = -3*4 + 0
u= 12 m/s

Goat (12х4) + 1 + (-3)
+43+5+4
48 - +​

Answer 1

Answer:

1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. Maths delivers! Braking distance ... If the car is initially travelling at u m/s, then the stopping distance d m ... We will see later in these notes how this formula is obtained.
