Answer:
μ = 0.136
Explanation:
given,
velocity of the car = 20 m/s
radius of the track = 300 m
mass of the car = 2000 kg
centrifugal force


F c = 2666. 67 N
F f= μ N
F f = μ m g
2666.67 = μ × 2000 × 9.8
μ = 0.136
so, the minimum coefficient of friction between road surface and car tyre is equal to μ = 0.136
Quality is how good something is. Like how good the material is. Like the quality of the IPhone X is better than the quality of the iPhone 6s + because it has more features and can sustain better hold
Quantity is how much. Like the quantity of the m&ms were split evenly.
I dont know exactly if that makes sense but there ya go
YW!
Answer:
c is the answer because we have to double the number
Answer:
Below is the desired C++ program for the problem. Do feel free to edit it according to your preference
Explanation:
#include <iostream>
#include <vector>
using namespace std;
void ExactChange(int userTotal, vector<int> &coinVals) {
coinVals.reserve(5);
coinVals[0] = userTotal / 100;
userTotal %= 100;
coinVals[1] = userTotal / 25;
userTotal %= 25;
coinVals[2] = userTotal / 10;
userTotal %= 10;
coinVals[3] = userTotal / 5;
userTotal %= 5;
coinVals[4] = userTotal;
}
int main() {
vector<int> coins;
int value;
cin >> value;
if (value <= 0) {
cout << "no change" << endl;
} else {
ExactChange(value, coins);
if (coins[0] != 0) cout << coins[0] << " " << (coins[0] == 1 ? "dollar" : "dollars") << endl;
if (coins[1] != 0) cout << coins[1] << " " << (coins[1] == 1 ? "quarter" : "quarters") << endl;
if (coins[2] != 0) cout << coins[2] << " " << (coins[2] == 1 ? "dime" : "dimes") << endl;
if (coins[3] != 0) cout << coins[3] << " " << (coins[3] == 1 ? "nickel" : "nickels") << endl;
if (coins[4] != 0) cout << coins[4] << " " << (coins[4] == 1 ? "penny" : "pennies") << endl;
}
return 0;
}
