The metric unit of length that is equal to one thousandth of a meter is a millimeter. 1 meter = 1000 millimeter
hope this helps
It is best to use mental math with some equations (5x5 or something that is easy enough that work does not have to be shown 10 dived by 5
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:
The given fraction is:

We need to solve it.
The LCM of 168 and 180 is 2520.
So,

So, the required answer is equal to
