Answer:
The average acceleration of train is
Step-by-step explanation:
We have,
A train that slows down from 15 m/s to 8.6 m/s in 1.2 s. It means that 15 m/s is its initial velocity and 8.6 m/s is its final velocity.
It is required to find the average acceleration of the train.
The average acceleration of train is . Negative signs shows that the train is decelerating.

Slope :
---------------------------------------
y = -5x + 2
Slope = -5
---------------------------------------
y - intercept :
---------------------------------------
At (0. 3), y-intercept = 3
---------------------------------------
Equation :
---------------------------------------
y = mx + b
y = -5x + 3
---------------------------------------
Answer : y = -5 + 3

Answer:
x = 7.99 cm
Step-by-step explanation:
By applying cosine rule in the given triangle,
AC² = AB² + BC² - 2(AB)(AC)cosC
Substitute the measures of the sides and the angle in this formula,
x² = 6² + 10² - 2(6)(10)cos(53°)
x² = 36 + 100 - 72.217
x² = 63.782
x = √(63.782)
x = 7.99 cm
