Average speed = (distance covered) / (time to cover the distance)
= (200 miles) / (5.5 hours)
= (200/5.5) mile/hour
= 36.4 miles per hour (rounded)
It would weigh less bc the higher you are the less gravity there is.
you may just select the word answer and then without cutting it u may start to type ur answer then it will be in bold letter

Answer:
a = 1 m/s²
Explanation:
given,
mass of the person = 60 Kg
Net External force exerted = 90 N
force of friction opposing the motion = 30 N
acceleration of the box = ?
Net force = External force applied - frictional force
Net force = 90 - 30
net force = 60 N
we know
F = mass x acceleration
60 = 60 x a
a = 1 m/s²
acceleration of the box is equal to a = 1 m/s²
The maximum height that is reached by an object thrown or jumped at a certain initial velocity can be calculated through the equation,
2ad = Vf² - Vi²
Vf is zero (0) in this equation because this is the point at the velocity at the maximum height of the object.
Substituting the known values,
2(a)(-16) = 0 - (3.6)²
The value of a from the equation is 0.405 m/s².
<em>Answer: 0.405 m/s²</em>
