Answer:
Explanation:
In order to know the value of the speed at any time t, we need to integrate the acceleration. Once we get the speed vs time, we need to integrate again to get the distance traveled by the motorcycle vs time. So let's start with the speed first:
We will integrate once again to get distance:
Now we just need t evaluate S(10s):
S(10) = 133.3m
For the acceleration, we know that:
where
and
So, finally:
Answer:
Explanation:
In the diagram there three gears in which gear 1 is input gear ,gear 2 is idle gear and gear 3 is out put gear.
Lets take
All external matting gears will rotates in opposite direction with respect to each other.
So the speed of gear third can be given as follows
Answer:
9.248 < < 9.253 mm
Explanation:
Given data:
standard deviation = 0.021 mm
sample mean = 9.251 mm
total sample = 409 m
confidence interval level = 95%
mean diameter of entire batch
where
- sample mean = 9.251 mm
z = critical value
plugginf all value in the above relation to get the mean diameter
9.248 < < 9.253 mm
