Explanation:
honestlyyy like what do they get out of it
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 vertical component of
this acceleration will be:
A= mgsin^2 <span> θ</span>
The downward fforce exerted by the hamster on the block and
on the scle will be
F = -ma
The reading will be like this:
Reading = Mg + mg sin^2 θ
= (0.820) (9.8) +
(0.190) (9.8) sin^2 (0)
<span>Reading = 8.036 N</span>
Looks like a double covalent bond.
