Explanation:

When water vapor in the air comes into contact with something cool, like the ceiling of a tent, its molecules slow down and get closer together. When that happens, the gaseous water vapor turns back into liquid water droplets. That's condensation!

a bicyclist initially at rest speeds up steadily during this time interval she averages 3.50 miles per second determine the init
Kobotan [32]

Answer:

Explanation:

Given parameters:

Average speed  = 3.5miles per second

Unknown:

Initial speed  = ?

Average speed  = ?

Final speed in the interval = ?

Solution:

Since the bicyclist started from rest and speeds up steadily, it is correct to assume that her starting or initial speed is 0m/s.

At a state of rest, a body has no speed.

Average speed is the sum total of the speed covered at each time interval. This value is given already to be 3.5miles per second.

Final speed is the speed before the bicycle halts. This speed will be the same as the average speed here which is 3.5miles per second.

Speed is the rate of change of distance with time.

____________________ when objects collide, the total initial momentum equals the total final momentum
Alexus [3.1K]
The law of conservation of linear momentum says that when objects collide, the total initial momentum equals the total final momentum.
The momentum of a body is given by the product of mass and velocity of the object.
