Answer:
25m
Explanation:
Let's assume the Jeep attains a velocity of 36km/h ; a constant speed same with that of the car.
While the Jeep is accelerating to that speed, the car with that speed passes it.
Now we can calculate the time taken for the Jeep to attain the velocity of 36km/h on her constant acceleration.
This time is t = v/a; from Newton's Law of Motion:
a = V-U / t ; a-acceleration
V is final velocity = 36km/h
U is initial velocity 0 since the body starts from rest.
Hence t = 36000/3600 ÷ 4 = 2.5s
Note conversting from km/h to m/s we multiply by 1000/3600.
But the distance covered by the car while the Jeep just accelerates is
S = U × t = 10× 2.5 = 25m.
Note From Newton's law of Motion, distance for constant speed is defined as: U × t
Hence the Car would be 25m off the starting point just as the Jeep accelerates. It would overtake the Jeep when it just covers 25m from the Jeep starting point.
Answer:
Explained
Explanation:
Given:
Ship travels due east from the Bar Harbor 38 miles before turning north
Yes it possible to calculate the exact direction of the ship by assuming there are no large islands in the way, and that the isolated ship does not cut off very far, then what we have here is a right triangle with a 72-mile as hypotenuse and a 38-mile as "adjacent" side. If θ is the angle out of Bar Harbor, we can write
, and θ = 58.14457°, or 58° 8' 40" north of east. That will be the exact direction.
When we dissolve NaCl in water, the ions are held in a rigid cage of water molecules. It takes less energy to activate these molecules, so the specific heat of the water decreases. The greater concentration of NaCl, the lower the specific heat capacity of the solution.
The ozone layer blocks the rays. But the ozone layers now has holes.
