Two forces act on a 16 kg object. The first force has a magnitude of 68 N and is directed 24 degrees north of east. The second f
Vlada [557]

Answer:

The correct Answer to the question is : e) 4.1 m/s^2, 52 degrees north of east

Explanation:

F1= 68 N < 24º = 62.12 i + 27.65 j

F2= 32N < 132º = -21.41 i + 23.78 j

R= F1+F2= 40.71 i +51.43 j = 65.59 N < 51.63 º

By 2nd law of newton:

F= m * a

R= m*a

a= R/m

a= 4.1 m/s² < 52º  (52 degrees north of east)

I consideer 0º at the EAST axis.

Two drag cars race. They line up at the starting line at rest. The winning car accelerates at a constant rate a and reaches the
Mila [183]

Answer:d=\frac{v^2}{8a}

Explanation:

Given

winning car accelerates with a and its final velocity is v

considering they both start from rest

time taken by winning car is

v=u+at

where u=initial velocity

a=acceleration

t=time

v=at

t=\frac{v}{a}

Now loosing car is accelerating with \frac{a}{4}

Distance traveled by loosing car in time t

s_1=ut+\frac{at^2}{2\cdot 4}

s_1=0+\frac{a}{8}\times (\frac{v}{a})^2

s_1=\frac{v^2}{8a}

Thus distance d traveled by loosing car is given by d=\frac{v^2}{8a}

Four bicyclists travel different distances and times along a straight path. Which cyclist traveled with the greatest average
riadik2000 [5.3K]

Answer:

The cyclist with the greatest average speed is Cyclist 4 with average speed of 4.5 m/s

Explanation:

Given;

Cyclist 1 travels 9 m    in    27 s

Cyclist 2 travels 87 m  in    22 s

Cyclist 3 travels 106 m  in   26 s

Cyclist 4 travels 108 m   in   24 s

Determine the average speed of the cyclists as follows;

Average speed of Cyclist 1:    v =  9/27  = 0.33 m/s

Average speed of Cyclist 2:    v = 87/22 = 3.96 m/s

Average speed of Cyclist 3:    v =   106/26 = 4.08 m/s

Average speed of Cyclist 4:     v =   108/24 = 4.5 m/s

Therefore, the cyclist with the greatest average speed is Cyclist 4 with average speed of 4.5 m/s
