V=5
W= 6
Check by putting in the answer
5+6=11
11=11
2(5)+6=16
10+6=16
16=16
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.
235/4 equals 58.75
Hope this helps!
I think it’s the last one but I’m not sure. Let me know if you get it right.
