Answer:
16.75
Step-by-step explanation:
The number 4 in 16.748 is in the hundredths place.
The number right behind it is 8, which is greater than or equal to 5...
...meaning that it should round up! Not stay the same.
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.
