Option C is the correct answer
Explanation:
Distance travelled by car during reaction time
The car stopped before hitting the animal by 
Distance travelled during deceleration is 
Hence by 
We have
Option C is the correct answer
Answer:
change the
Explanation:
P = W/time
W = F*d
You have control over how fast you go up the stairs.
You also have control over how far up the stairs you go.
Therefore the answer is
If you don't like distance as an answer, you can carry something up the stairs -- anything that increases F will do.
V = u + at
0 = u -9.8 x 5.5
u = 9.8 x 5.5 = 53.9 m/s
Answer:
The forces creating the net force must lie in the same direction.
Explanation:
newton's second law states that the net force acting on the body is equal to the product of mass and the acceleration of the body.
If there are several forces acting on the body in different directions, then we have to find teh net force by using the vector sum and then find the acceleration.
It is not necessary that all the forces acting in the same direction.
if they are in different directions then we have to find the net force by t=using the formula for the vector sum.
Uhhhh...you should have paid attention in class, just saying...
