Answer:
6.4331 × 10 5N
Step-by-step explanation:
Given the following :
Mass (m) of car = 1200kg
Initial Velocity (u) of car = 60 mph
Final velocity = 0 ( comes to rest)
Velocity in m/s = 60 / 2.24 = 26.785 m/s
Time (t) = 0.0500
Using the relation :
Ft = m(v - u)
Where,
v = final velocity ; u = initial velocity ; t = time ; F = force
F*0.05 = 1200(26.785 - 0)
0.05F = 32142.86 - 0
F = 32142.86 / 0.05
F = 642857.14 N
F = 6.43 × 10^5 N

Answer:
2.1 hours (2 hours and 6 minutes)
Step-by-step explanation:
The rate of work of Bobbi is ⅓ while for Deshaun is 1/7 hence combined rate will be
⅓+1/7=(7+3)/21=10/21
The equivalent hours is the reciprocal of the above hence 1021/10=2.1 hours
0.1 of an hour is equivalent to 0.1*60=6 minutes
Therefore, the efforts combined will take 2.1 hours or 2 hours and 6 minutes
Hi DoraTheExplorer36!
In order to solve number 10:
area of a circle : A=pie * radius (r) squared
A=πr2
Radius is half of a circle and diameter is a full line across a circle
Solve :
A=πr2
A= 3.14 * 11 (radius) 2
1193.0116
Rounded to the nearest whole number is : 1193.
Your answer would be 1193.
Hope that helped! :)
