The speed after 10 s is 20 m/s

<h3>What is the speed after 10 s?</h3>

Given that we have the following;

force = 2800 N

Mass = 1400 kg

time = 10 s

Recall that;

F = ma

F = force

m = mass

a = acceleration

a = F/m

a =  2800 N/1400 kg

a = 2 m/s^2

Now;

v = u + at

v = ??

u = 0 m/s

a= 2 m/s^2

t = 10 s

v = at

v = 2 * 10

v = 20 m/s

What is the anomalous expansivity of water
salantis [7]

Answer:

The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4°C to 0°C, and it becomes less dense. The density becomes less and less as it freezes because molecules of water normally form open crystal structures when in solid form.

A worker uses a cart to move a load of bricks a distance of 10m across a parking lot. if he pushes the cart with a constant forc
andriy [413]

Answer:

2090 J

Explanation:

the work done to move the cart is equal to the product between the force applied and the distance traveled:

W=Fd

In this case, the force applied is F=209 N, while the distance covered is d=10 m, therefore the work done is

W=Fd=(209 N)(10 m)=2090 J

An 56 kg sled is being pulled across the snow, at constant speed,by a horizontal force of 15 N, find the coefficient of kinetic
Stolb23 [73]

Answer:

The coefficient of  kinetic friction = 0.026  

Explanation:

An 56 kg sled is being pulled across the snow, at constant speed,by a horizontal force of 15 N.

Here we have to note that the weight is pulled at a constant speed . This means that the net force acting on the weight is zero.

The external force acting on the body is in the forward direction and the friction acts in the backward direction.

Friction increases as the mass of the body increases.

Friction = u_{k}\times m \times g

We now equate this to the external force of 15 N.

15 = u_{k} \times 56 \times 10

u_{k} = \frac{15}{560}

u_{k} = 0.026

The coefficient of  kinetic friction = 0.026
