Answer:
0.6944 m/sec^2
Explanation:
The computation of the average acceleration is given below:
a = v - u ÷ t
where
a denotes average acceleration
v denotes final velocity
u denotes initial velocity
t denotes time
So, the average acceleration is
= (25 - 0) ÷ 10
= 0.6944 m/sec^2
Answer:
Yes, there will be collision.
Explanation
Initial relative velocity u = 34-5.4 = 28.6 m/s
required final relative velocity v = 0
Acceleration , suppose be a .
Distance traveled =d = 160 m
Using the formula for relative motion,
v² - u² = 2as
0 - 28.6²=2as
a = - 2.55 m s⁻².
Since this required value is more than maximum braking deceleration so , there will be collision.
