| The body passed 120 m in the fifth second of movement, moving from a state of rest. Find the acceleration of the body. What is the distance the body will cover in 10 seconds.
To solve the problem, we need the following formula:
S = a * t ^ 2/2;
Now we need to transform it to find a:
a = 2 * S / t ^ 2;
Substitute and find acceleration:
a = 2 * 120/10 ^ 2;
a = 240/100;
a = 2.4
We return to the initial formula and substitute:
S = 2.4 * 10 ^ 2/2;
S = 240/2;
S = 120.
Answer: S = 120.
