Answer:
The rate of change of the distance is 14.89.
Explanation:
Given that,
Distance = 145 miles
Speed of car = 42 miles/hr
Distance covered by car = 55 miles
We need to calculate the the rate of change of the distance
According to figure,
Let OA is x, and AB is y.
Now, using Pythagorean theorem
On differentiating
Hence, The rate of change of the distance is 14.89.
Answer:
0.44807175m
Explanation:
k = Spring constant = (Assumed, as it is not given)
g = Acceleration due to gravity = 9.81 m/s²
Total mass is
The total weight will balance the spring force
The springs are compressed by 0.44807175m
