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.
Answer:
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
Now loosing car is accelerating with 
Distance traveled by loosing car in time t
Thus distance d traveled by loosing car is given by

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
