Answer:
C = 10
Step-by-step explanation:
a²+b² = c²
36 + 64 = c²
100 = c²
C = √100
C=10
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:
IMAGE 1: positively skewed because it is skewed more to the right
IMAGE 2: symmetric because, well, it's symmetric.
IMAGE 3: negatively skewed because it is skewed to the left.
