given,

mass of bicyclist(m)=90Kg

centripetal acceleration(a)=1.5 m/s2

centripetal force(F)=ma= 90×1.5=145 N

Answer:

Force, F = 135 N

Explanation:

Given that,

Mass of the bicyclist, m = 90 kg

Centripetal acceleration of the bicyclist, a=1.5\ m/s^2

To find,

The centripetal force acting on the bicyclist.

Solution,

When an object moves in a circular track, it will under the action of centripetal acceleration and the exerted force is called centripetal force. It can be calculated as :

F=ma

F=90\ kg\times 1.5\ m/s^2

F = 135 N

So, the centripetal force acting on the bicyclist is 135 N.

What does the area between the line and the x-axis represent on a velocity vs. time graph?
Finger [1]

Answer:

It has been learned in this lesson that the area bounded by the line and the axes of a velocity-time graph is equal to the displacement of an object during that particular time period. ... Once calculated, this area represents the displacement of the object.

jolli1 [7]

Your answer is B.

The relationship between medium temperature and speed of sound is a direct relationship: when one factor increases, the other increases as is shown in graph B. The British would choose the the time of day which would give the lowest speed of sound, because this would be easiest to break. Graph B shows that the lowest speed of sound would occur with the lowest air temperature - in the morning.

musickatia [10]

Answer:

(C) greater than zero but less than 45° above the horizontal

Explanation:

The range of a projectile is given by R = v²sin2θ/g.

For maximum range, sin2θ = 1 ⇒ 2θ = sin⁻¹(1) = 90°

2θ = 90°

θ = 90°/2 = 45°

So the maximum horizontal distance R is in the range 0 < θ < 45°, if θ is the angle above the horizontal.
