Answer: divide by zero, or square root of a negative
Explanation: If your question is how to get infinity as an answer to a problem, that generally means that the answer is undefined or doesn't exist.
A couple of ways to get that...
- You try to divide by zero. In other words, a problem that asks you to perform something like this: 5/0= or 23/(4-4)= Such a problem will give you an error on a calculator because the answer is infinity or doesn't exist.
- Another way is to try to get the square root of a negative number. That answer doesn't exist as a real number, so
will also give you an error on a calculator.
Answer:
t = 1.22 s
Explanation:
Given that,
The initial upward velocity component of a football = 12 m/s
The horizontal velocity component is 20 m/s
We need to find the time required for the football to reach the highest point of the trajectory. Let the time is t.
Using first equation of motion to solve it such that,
u is initial velocity
v is final velocity
a = -g
so,
So, the required time taken by the football to reach the highest point is 1.22 seconds.
