Answer 1

Дано:
t=1c
S=5м
Найти:S1(t=4c),a,S2(t=5c)
Решение:
S=$\frac{at ^{2} }{2}$    a=$\frac{2S}{t ^{2} }$
a=10 м/с^2
S1=160/2=80м
S2=250/2=125м
Ответ:a=10м/с^2 , S1=80 м , S2= 125м

Answer 2

Given:

- Initial velocity of the block, u = 0 m/s (since it starts from rest) - Distance covered in the first second, s = 5 m

To Find:

1. The total distance covered by the block in the first 5 seconds. 2. The distance covered by the block in the fourth second. 3. The acceleration of the block.

Solution:

1. To find the total distance covered by the block in the first 5 seconds, we can use the equation of motion:

s = ut + (1/2)at^2

Here, s is the distance covered, u is the initial velocity, t is the time, and a is the acceleration.

Since the block starts from rest, the initial velocity u is 0 m/s. Therefore, the equation simplifies to:

s = (1/2)at^2

Plugging in the values, we have:

5 = (1/2)a(1)^2

Solving for a, we get:

a = 10 m/s^2

Now, we can find the total distance covered in the first 5 seconds using the same equation:

s = ut + (1/2)at^2

Plugging in the values, we have:

s = 0(5) + (1/2)(10)(5)^2

Simplifying, we get:

s = 125 m

Therefore, the block will cover a total distance of 125 meters in the first 5 seconds.

2. To find the distance covered by the block in the fourth second, we can use the equation of motion:

s = ut + (1/2)at^2

Plugging in the values, we have:

s = 0(4) + (1/2)(10)(4)^2

Simplifying, we get:

s = 80 m

Therefore, the block will cover a distance of 80 meters in the fourth second.

3. The acceleration of the block is given by a = 10 m/s^2.

Therefore, the block is moving with an acceleration of 10 m/s^2.

Answer:

1. The block will cover a total distance of 125 meters in the first 5 seconds. 2. The block will cover a distance of 80 meters in the fourth second. 3. The block is moving with an acceleration of 10 m/s^2.
