Answer:
A.) Acceleration = 4.6 m/s^2
B.) Average speed = 47 m/s
Step-by-step explanation:
A.) From the graph, at t = 10s,
Velocity V = 46 m/s
Acceleration a = (change in V)/ time t
a = (46 - 0)/10
a = 46/10 = 4.6 m/s^2
B.) If we estimate the speed at 5 seconds intervals, then we have
Average speed = (36 + 46 + 49 + 50 + 50 +50 + 50) ÷ 7
Average speed = 331/7 = 47.29 m/s
Average speed = 47 m/s

This question is incomplete because it lacks the appropriate figure. Find attached to this answer the diagram of the figure.
Answer:
8%
Step-by-step explanation:
The formula for Probability =
Numbers of possible outcomes ÷ Number of events.
From the diagram, Number of Possible outcomes is given as = Number of Adults that prefer auto racing = 179 adults
Number of events is obtained from the questions as the Number of Adults = 2237 adults
Probability that an adult chosen at random prefers auto racing = 179 adults /2237 adults
= 0.0800178811
Rounding my answer to the nearest whole percent, the probability that an adult chosen at random prefers auto racing
= 0.0800178811 × 100
= 8%
