Answer 1

Answer:

$V = U + at$

Step-by-step explanation:

Given the following data;

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;

$V = U + at$

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;

$32 = 0 + 10*3.2$

$32 = 0 + 32$

$32 = 32$

Proven: 32 m/s = 32 m/s
