The average speed of Frank's car is 2 m/s and the average speed of Noah's car is 1.8 m/s.
<u>Explanation:</u>
Average speed is the measure of total distance covered at different time period. Since, the formula used for calculating the average speed is the ratio of total distance covered by each car to the time taken to cover that distance.
As there is only one set of data i.e., distance and time, the average speed will be equal to the speed of the car.
So in this case, the total distance covered by franks car is 300 cm = 3 m in 1.5 s. Then, the average speed will be
Similarly, the average speed of Noahs car which rolled a distance of 360 cm = 3.6 m in time 2 s, will be
Thus, the average speed of Frank's car is 2 m/s and the average speed of Noah's car is 1.8 m/s.
Hey There!
The atomic number represents the electrons and protons, therefore, if the atomic number of the element is 7 then there are 7 electrons and protons in the element.
In order to determine the amount of neutrons, you would subtract the atomic number from the atomic mass.
Hope this helped!
They will both hit the ground at the same time due to gravity.
that means they took the same time to travel the distance to the ground
however, the ball traveled farther
speed=distance (or displacement) divided by time
so the greater the distance, the greater the speed
the ball traveled faster in the same time so it traveled faster
answer is ball
Not so fast.
I think you're using 'accelerating' to mean 'speeding up', but you really need
to be more careful with it. "Acceleration" means ANY change in speed OR
direction.
If an object's speed to the left is decreasing, or its speed to the right is
increasing, then the net force on the object must be directed towards
the right.
If an object is moving with constant speed in a circular path, then it's
constantly accelerating, because its direction is constantly changing.
The force on it is always directed towards the center of the circle, so
there's one point on the path where the force is directed straight to the right.
its 13.98. it's simple multiplication 3* 4.66= 13.98
