Question

Мальчик стоящий на тележке тянет за веревку прикрепленную к стенке с силой 80 H при этом тележка за одну секунду приобрела скорость 2 метров секунду Какое ускорение приобрело тележка Какова масса мальчика вместе с тележкой

Answer 1

F=80
V=2
t=1
a=?
m=?
a=v/t=2
m=F/a=40

Answer 2

Calculation of Acceleration and Mass

To calculate the acceleration acquired by the cart and the mass of the boy together with the cart, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Given: - Force applied by the boy: 80 H - Velocity acquired by the cart: 2 m/s - Time taken: 1 second

We can use the formula:

Force = Mass x Acceleration

From the given information, we can calculate the acceleration of the cart and the mass of the boy together with the cart.

Let's calculate the acceleration first.

Acceleration = (Velocity acquired) / (Time taken)

Acceleration = 2 m/s / 1 s = 2 m/s^2

Now, let's calculate the mass.

Mass = Force / Acceleration

Mass = 80 H / 2 m/s^2 = 40 kg

Therefore, the cart acquired an acceleration of 2 m/s^2, and the mass of the boy together with the cart is 40 kg.
