Two horses, Thunder and Misty, are accelerating a wagon 1.3 m/s2. The force of friction is 75 N. Thunder is pulling with a force
just olya [345]

Answer:

1327 kg

Explanation:

So the net force exerted on the wagon would be the sum of forces from 2 horses subtracted by friction force

F = 1000 + 800 - 75 = 1725 N

This force results in an acceleration of a = 1.3 m/s2. We can use Newton's 2nd law to calculate the mass of the wagon

F = ma

m = F / a = 1725 / 1.3 \approx 1327 kg

An object is dropped from 42m tall building. How long does It take to reach the ground?
yKpoI14uk [10]

Answer:

It takes <u>2.93 s</u> for the object to reach ground from the height of 42 m.

Explanation:

Given:

Displacement of the object is, d=-42\ m

As it is dropped, initial velocity of the object is, u=0

Acceleration of the object is equal to acceleration due to gravity and is equal to, a=g=-9.8\ m/s^2

Now, using Newton's equation of motion and plugging in the values, we get:

d=ut+\frac{1}{2}at^2\\-42=0+\frac{1}{2}(-9.8)t^2\\-42=-4.9t^2\\t^2=\frac{-42}{-4.9}\\t^2=8.571\\t=\sqrt{8.571}=2.93\ s

So, it takes 2.93 s for the object to reach ground from the height of 42 m.
