Height of one roof is 5.97 m below the other roof
now its displacement in vertical direction is given as
solving above for time
now in the same time cat has to cover the distance between two buildings
so here we can say
solving above for speed
so speed of cat is 6.54 m/s
We'll find the car's speed first, and then use that to find the velocity.
Speed = (distance covered) / (time to cover the distance)
Speed = (240 miles) / (3 hours)
Speed = (240/3) · (miles/hours)
Speed = 80 mile/hour
Now to convert the units, we'll use
-- 1 mile = 1,609 meters
-- 1 hour = 3,600 seconds
(80 miles/1 hour) · (1,609 meter/1 mile) · (1 hour/3,600 second) =
(80 · 1,609 · 1) / (1 · 1 · 3,600) (mile · meter · hour / hour · mile · second) =
35.76 meter/second
Now, to make a velocity, all we need to do is to add the direction to the speed.
So the car's <em>velocity</em> is <em>80 mi/hr south</em>, or <em>35.76 meter/sec south</em> .
The time period for guilty party was between 1900-1988.
Answer:
Please find here some hints :
Rule. Newton’s second law, or fundamental principle of dynamics, mentions that a resultant force exerted on an object is always equal to the product of the mass of that object by its acceleration. ... Each force applied to an object causes this object to accelerate in the direction of the force applied.
Is acceleration a force?
The acceleration force, sometimes called the inertia force, is the vehicle’s resistance to speed variations. It holds you back when you increase your speed and pushes you back when you slow down.
