Answer:
Explanation:
The acceleration of the car is given by:
where
v is the final velocity
u is the initial velocity
t is the time
Here we have to convert the velocities from mi/hr to m/s. Keeping in mind that
1 mi = 1609 m
1 h = 3600 s
We get:
While the time interval is
t = 4.0 s
Substituting,
Y is -45 N and X is 30.
When learning about forces, you have to understand that everything will cancel out on an object. So if the normal force is 45, to cancel it, the force of gravity has to be the negative of it. The same idea goes to frictional force. If the frictional force is -30 N, then to cancel it out, it has to be 30 N.
As the water plunges, its velocity increases. Its potential energy<span> becomes kinetic</span>energy<span>. The law of conservation of </span>energy<span> states that when one form of </span>energy<span> is</span>transformed<span> to another, no </span>energy<span> is destroyed in the process. ... So the total amount of </span>energy<span> is the same before and after any </span>transformation<span>.
