A, C, and D are true when a light spot appears, so those are false.
The answer is therefore B.
Answer:
Total distance traveled= 75.36km (point at which she reaches her destination.)
Explanation:
With the speed and time data we can calculate the distance traveled on each path, but first we must transform the time units from minutes to hours:
First ride:
v=80km/h t=25min*1h/60min=0.42h
distancie= v*t = 80km/h * 0.42h =33.6km
Second ride:
v=65.0km/h t= 20min*1h/60min= 0.33h
distance= 65.0km/h*0.33h=21.67km
Stop: 60min= 1h distance=0km
third ride:
v= 40.0km/h t= 30.0min *1h/60min= 0.5h
distance= 40.0km/h*0.5h=20km
Total distance traveled= 33.6km +21.76km+20km
Total distance traveled= 75.36km
Answer:
Woke done, W = 4156.92 Joules
Explanation:
The work done by the force can be calculated as :
is the angle between force and the displacement
It is assumed to find the work done for the given parameters i.e.
Force, F = 30 N
Distance travelled, s = 160 m
Angle between force and displacement, 
Work done is given by :
W = 4156.92 Joules
So, the work done by the object is 4156.92 Joules. Hence, this is the required solution.
The correct answer would be 4 seconds
it is A.
Because B. Is just way off
C. Is just straight
And D. Is just....yea
