Answer:

$a = \frac{(v - u)}{t} \\ v - u = at \\ v = at + u$

ii.

$a = \frac{(v - u)}{t} \\ v - u = at \\ u = v - at$

iii.

$a = \frac{(v - u)}{t} \\ ta = v - u \\ t = \frac{(v - u)}{a}$

I hope I helped you^_^

What is the smallest radius of an unbanked (flat) track around which a bicyclist can travel if her speed is 32 km/h and the coef

Leviafan [203]

Answer: 29.83m

Explanation: coefficient of friction= v^2/rg

Coefficient of friction=0.27

V=32km/h

Convert km/h to m/s

32*1000/3600

32000/3600=8.89m/s

0.27=8.89^2/r*9.81

0.27*9.81*r=79.0321

R= 79.0321/2.6487

R=29.83m

A motorcycle slows down uniformly from a speed of 21 m/s to rest in 6.0s. How far did it travel during this time?

Verizon [17]

Answer:

63 m

Explanation:

The initial velocity of the motorcycle is

$v_i = 21 m/s$

The final velocity is

$v_f = 0$

And the time taken is

$t=6.0 s$

Since the acceleration of the motorcycle is uniform, we can find the distance traveled by the motorcycle during this time by using the following SUVAT equation:

$S=\frac{1}{2} (v_i +v_f) t$

Substituting numbers into the equation, we find

$S=\frac{1}{2}( 21 m/s + 0)(6.0 s)=63 m$

3. Consider a locomotive and the rest of a freight train to be a single object. Suppose the locomotive is pulling the train up a

34kurt

Answer:

The friction force and the x component for the weight should be the reaction forces that are opposite and equal to the action force, which causes the locomotive to move up the hill if the velocity of the locomotive remains constant.

Explanation:

When the locomotive starts to pull the train up, appears two reaction forces opposed to the action force in the direction of the move.

The first one is due to the friction between the wheels and the ground, it will be the friction force (Fr):

Fr = μ*Pₓ =μmg*sin(φ)

where μ: friction dynamic coefficient, Pₓ: is the weight component in the x-axis, m: total mass = train's mass + locomotive's mass, g: gravity, and sin(φ): is the angle respect to the x-axis.

And the second one is the x component for the weight (Wₓ):

Wₓ = mg*cos(φ)

where cos(φ): is the angle respect to the y-axis.

These two forces should be the same as the action force, which causes the locomotive to move up the hill if the velocity of the locomotive remains constant.
