Answer:
12.35m
Explanation:
Hello! To solve this problem we must consider the following:
1. The car moves with constant speed, which means that the distance traveled is equal to the multiplication of time by speed.
X = VT
we solve the equation for time
2. The bolt moves with constant acceleration, with acceleration of 9.81m / s ^ 2, so we could apply the following equation.
note=remember that "a uniformly accelerated motion", means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.
where
Vo = Initial speed
=0
T = time
=1.588s
g =gravity=9.8m/s^2
Y = bridge height
solving
Answer:
The number of cell phone users increases every year.
Explanation:
Cell phone providers want people to buy cell phones because they make money off of it. The other two options might cause people not to want a cell phone, which could potentially harm their business.
60 miles / hr
= 60 * 1.6 * 1000 m / 60 * 60 s
= 96000 m / 3600 s
= 26.67 m / s
The force of friction that is acting on the suitcase is the force that opposes the motion of the suitcase.
<h3>What is friction?</h3>
The force that resists the motion between two bodies in contact. There are some materials that reduces friction such as oil in a car engine reduces friction. In this example, friction creates between the motion of suitcase and with the ground.
So we can conclude that the force of friction that is acting on the suitcase is the force that opposes the motion of the suitcase.
