If you are going 30 miles an hour in good condition, it will take how many feet to stop .
Answer:
158400 feet per hour
Explanation:
First we find:
How many feet are in miles per hour?
Multiply your speed in miles per hour by 5,280. This is the number of feet in a mile. The result is your speed in feet per hour.
For example, 30 miles per hour times 5,280 feet per mile is 158,400 feet per hour.
Your pet hamster sits on a record player whose angular speed is constant. If he moves to a point twice as far from the center, then his linear speed
A) doubles.
B) halves.
C) remains the same.
Answer:
option A
Explanation:
given,
angular speed is constant
initial distance = r
final distance (r')= 2 r
initial linear velocity = v
final linear velocity = v'
we know,
v = r ω......................(1)
where r is the distance
ω is the angular speed
now,
v' = r' ω
v' = 2 r ω
v' = 2 v
hence, the linear velocity doubles.
The correct answer is option A
