Answer:
could you explain more?
Step-by-step explanation:
Of getting less than 7: 100%
of getting a number greater than or equal to 3: 4/6 or 67%
2x+3y·3y+2x=z
2(3.2)+3y<span>·3y+2(3.2)=457.96
6.4+9y+6.4=457.96
12.8+9y=457.96
-12.8=-12.8
9y=445.16
/9=/9
y=49.46222222
y=49.46</span>
I believe this is -5, hope it helped
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
