Answer:
Force on the object is 20 N
Explanation:
As we know that work done to raise the book from initial position to final position is known as potential energy stored in it
So here we know that
here we know that
U = 30 J
s = displacement = 1.5 m
so we have
Average velocity over a given time interval is the distance traveled divided by the time:
Answer:
After it finishes speeding up, the car goes 72 [m]
Explanation:
To solve this problem we must first understand the graphics. It is clear that in the last 6 seconds, that is, from the fourth to the tenth second, the car moves at a constant speed.
Therefore in this time interval, the car moves at a constant speed.
With the following equation of kinematics, we can calculate the distance traveled.
where:
x = final point [m]
x₀ = initial point [m]
v = constant velocity = 12 [m/s]
t = time = 6 [s]
Now replacing we have:
