Answer:
19 nickels and 5 pennies
Step-by-step explanation:
Let x nickels and y pennies
100 = 5x + y
x + y = 24
y = 24 - x
100 = 5x + 24 - x
4x = 76
x = 19
y = 24 - x = 24 - 19 = 5
From the moment the friend passes the bicyclist, his friend covers a distance over time t of (3.63 m/s)*t.
The bicyclist covers a distance of 1/2*(2.11 m/s^2)*t^2. They meet when these distances are equal:
3.63 t = 1.055 t^2 ==> 1.055 t^2 - 3.63 t = 0
==> t = 0 s or t = 3.44 s
