Answer:
8
Step-by-step explanation:
K.E=0.5mv^2
GPE=mgh
The child has both K.E and GPE
g is taken as 9.81
When it is in motion the force is unbalanced. When it stops the forces are balanced.
The answer is -|0.35 t -14| +14
<u>Step-by-step explanation</u>:
The problem statement is asking for an expression for distance in miles, so the constants in the expression will be miles. In the time it takes to get to point B (40 minutes), the ferry has gone (0.35 mi/min)×(40 min) = 14 mi. Hence the maximum value of the function must be 14. The only function with that characteristic is the one of selection D.
