Since the mass is moving in a horizontal circle, we do not look at gravity, tension in string or weight of the mass.
<em>
Time period for one cycle around circle = T = 0.42 seconds
</em>

<em>Tangential Velocity or speed of the mass = </em>
<em>         tangential distance traveled in 1 cycle or revolution / time period</em>
        = circumference of circle / time period
<em>       = 2 π radius / T  = 2 π 1 meter / 0.42 sec  </em>
<em>       =  14.96 m/s</em>

Determine the automobile’s braking distance from 90 km/h when it is going up a 5° incline. (Round the final value to one decimal
NeX [460]

Answer:

366 m

Explanation:

u = 90 km/h = 25 m/s,

theta = 5 degree

acceleration, a = g Sin theta = 9.8 x Sin 5 = 0.854 m/s^2

The final velocity os zero and let the braking distance be s.

Use third equation of motion

v^2 = u^2 - 2 a s

0 = 25 x 25 - 2 x 0.854 x s

s = 366 m
