A bicyclist slow with a force of 3.5 × 10² N. if the bicyclist and bicycle have a total mass of 1.0 × 10² kg, what is the accele
Aleonysh [2.5K]

Answer:

3.5 m/s²

Step-by-step explanation:

We are given;

  • The force of a bicycle as 3.5 × 10² N
  • Mass of the bicycle as  1.0 × 10² kg

We are required to determine the acceleration of the bicycle;

From Newton's second law of motion;

F = ma

Rearranging this;

a = F÷ m

Therefore;

Acceleration = 3.5 × 10² N ÷ 1.0 × 10² kg

                     = 3.5 m/s²

Thus, the acceleration of the bicycle is 3.5 m/s²

The perimeter of a rectangle is 158 cm. If the length is 7 more than 3 times the width:
Goryan [66]
Width of rectangle = x
Length =3x+7
Perimeter of rectangle = 158cm
2(l+w)=158
2(3x+7+x)=158
2(4x+7)=158
8x+14=158
8x=158-14
x=144/8
x=18
Therefore the width of the rectangle is 18cm
Length=3x+18+7
54+7=61cm
Area=lxw
=61x18
=1098^2

Determine the direction that this parabola opens y=4x^2+8x+2
just olya [345]
For this case we have a quadratic equation of the form:
 ax ^ 2 + bx + c

 What we must keep in mind to know which direction opens the parabola, is the value of a.
 We have two options:
 If a <0 the parabola opens down
 If a> 0 the parabola opens up
 We have the following equation:
 y = 4x ^ 2 + 8x + 2&#10;
 We observed that:
 a = 4 (a\ \textgreater \  0)&#10;
 Therefore, the parable opens up.
 Answer:
 
the direction that this parabola opens is:
 
Upwards
