What is the net force on a Mercedes convertible traveling along a straight road at a steady speed of 100 km/h?
luda_lava [24]

Answer:

5) 0 N

Step-by-step explanation:

According to Newton's second law of motion: "The acceleration of an object produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force and inversely proportional to the object's mass" .

Because the vehicle travels at a constant speed, its acceleration at zero, so

A=F_{net}/m,

F_{net}=A*m; A=0\\F_{net}=0

The table shows the percentage of students in each of three grade levels, and the percentage who list basketball as their favori
lions [1.4K]
First, let's find out what percentage of the total group of students lists basketball as their favorite sport:
10th: .41 * .4 = 16.4% of the school are 10th grade ballers
11th: .30 * .35 = 10.5% of the school are 11th grade ballers
12th: .29 * .40 = 11.6% of the school are seniors who drain like Kobe
Total:                    38.5% of all students list basketball as their favorite sport. 

We divide the portion of 10th grade basketball fans by the total proportion of basketball fans:
16.4% ÷ 38.5% = 42.6%

There is a 42.6% chance that the student is a 10th grader, given that he/she is a basketball fan.
