U= 9.4m/s
v= -7.4m/s (Negative sign because it is in the opposite direction as he is rolling back)
t= ?
s= ?
a= ?
Now, a= v-u/t
= -7.4-9.4÷3
=-5.6
By the second equation of motion.
s= ut+1÷2at*2 ( *2 is the power)
s= 9.4×3+1÷2×-5.6×3*2
= 28.2 +(-25.2)
=3
Therefore s or the distance travelled is 3m.
Answer:
Step-by-step explanation:
Answer:
The perimeter is 127.1 cm
Step-by-step explanation:
30+25+25=80
(2)(3.14)(15)=94.2
94.2/2=47.1
Divide by two because of the semicircle
80+47.1=127.1
3.06% becomes 0.0306 as a decimal, then you make it
306/10000
Simplify that:
153/5000
Hope this helped!
Answer:
y = 1/2x - 2
Step-by-step explanation:
Slope intercept form:
y = mx + b
x - 2y = 4
-2y = -x + 4
2y = x - 4
y = 1/2x - 2
