Answer:
7x^2 -x -5
Step-by-step explanation:
(8x^2 - 2x) - (x^2 - x + 5)
Distribute the minus sign
(8x^2 - 2x) - x^2 + x - 5
Combine like terms
7x^2 -x -5
Answer:
Step-by-step explanation:
<u>Given the following data;</u>
Initial velocity = 0 (since the stone is starting from rest).
Final velocity = 32 m/s
Acceleration = g = 10 m/s²
Time = 3.2 seconds
To show that the speed of the stone when it hits the ground is 32 m/s, we would use the first equation of motion;
Where;
- V is the final velocity.
- U is the initial velocity.
- a is the acceleration.
- t is the time measured in seconds.
Substituting into the formula, we have;

<em>Proven: 32 m/s = 32 m/s</em>
