Answer:
Final velocity v = 8.944 m/sec
Explanation:
We have given distance S = 40 meters
Time t = 10 sec
As it starts from rest so initial velocity u = 0
From second equation of motion
Now from first equation of motion , here v is final velocity, u is initial velocity, a is acceleration and t is time
So
The formula for average speed is
So we can just substitute our data.
- its the result
So we can just substitute our data.
Answer:
The length of the resultant vector is 50 inches
Explanation:
Use the Pythagorean theorem to find the answer, since the addition of these two perpendicular vectors will have a magnitude (length) equal to the hypotenuse of the right angle triangle formed by the two:
The length of the resultant vector is 50 inches
