Question

M=0.2 t=5 секунд 0.1 ньютона найти s v

Answer 1

Дано:

Vo=0

m=0.2 кг

t=5 c

F=0.1H

S-?

V-?

S=V0t+0.5at²

V=Vo+at

a=F/m   a=0.1/0.2=0.5 м/с²

V=0.5*5=2.5 м/с

S=0.5*0.5*25=6.25 м

Вроде так :)

Answer 2

To find the displacement (s) and velocity (v) of an object, given the mass (M = 0.2 kg) and time (t = 5 seconds) under a force of 0.1 Newton (N), we need to apply the laws of motion.

1. Newton's second law of motion relates force, mass, and acceleration: F = m * a where F is the force (0.1 N), m is the mass (0.2 kg), and a is the acceleration.

2. We need to find the acceleration. Using Newton's second law, we can rearrange the formula to solve for acceleration: a = F / m

3. Now, we'll use the acceleration to find the velocity (v): v = u + a * t where u is the initial velocity (we assume it to be 0, as it's not given).

4. Finally, we'll use the velocity to find the displacement (s): s = u * t + (1/2) * a * t^2

Let's calculate the values step by step:

Step 1: F = 0.1 N m = 0.2 kg a = F / m = 0.1 N / 0.2 kg = 0.5 m/s²

Step 3: u = 0 (initial velocity, assumed to be 0) t = 5 seconds v = 0 + a * t = 0 + 0.5 m/s² * 5 s = 2.5 m/s

Step 4: s = u * t + (1/2) * a * t^2 = 0 * 5 s + (1/2) * 0.5 m/s² * (5 s)^2 = 0 + 0.5 * 25 = 12.5 meters

So, the velocity (v) of the object after 5 seconds is 2.5 m/s, and the displacement (s) of the object during this time is 12.5 meters.
