Can one calculate the speed at which the car is traveling by only measuring the angle of the streaks from the vertical axis?

Homework Answers

Answer #1

No. By only measuring the angle of the straks from the vertical axis, you cannot determine the speed of the car.

Consider the motion of a car in an inclined plane. Suppose theta is the angle of the slope.

In the case when the slope is frictionless, the acceleration of the car towards the down side of the slope is given by -

a = g*sin theta

suppose the car starts from rest, then its speed after time t can be known using the expression -

v = u + a*t

put u = 0

so, v = (g*sin theta)*t

so the second variable we should have time t, for knowing the speed of the car.

Therefore, by only knowing the slope theta, we cannot determine the speed of the car.

a girl with a ball-on-a-string stands out of the sunroof of a car. She holds one end of the string and lets the ball hang freely. The car is traveling around a 40m radius curve on a horizontal track at a constant speed of 10m/s. Due to the car's turn the ball makes an angle theta with respect to the vertical direction as shown in the figure. Find theta with respect to the vertical direction as shown in the figure.
