Jerry is pushing a 50-kg box across a moth floor with an acceleration of 0.6 m/s2. What force is he applying to the box? *
vagabundo [1.1K]

Answer:

<h2>30 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 50 × 0.6

We have the final answer as

<h3>30 N</h3>

Hope this helps you

A large goose lands in a lake and bobs up and down for a short time. A fisherman notices that the first wave crest created by th
sleet_krkn [62]

Answer:

11.85m

Explanation:

For the development of this problem we must resort to the concepts of the basic kinematic equations that define the distance of a body, such as speed for a certain time, that is,

D=v*t

From the information provided we say that the distance between the cretas is 0.6m,

D_{crest} = 0.6m

In our information we have also that the length between the first and latest wave is in time terms of 2.2s. They are 4 waves in 3 intervals then

D_{T} = D_{crest}*3= 0.6*4 = 2.4m

t=1.6s

\upsilon = \frac{D_{T}}{t} = \frac{2.4}{1.6}

\upsilon = 1.5 m/s

Then the distance from the shore is given by the speed of the waves for the total time. That is

X = \upsilon*T\’

X = 1.5*7.9

X= 11.85m

A car travels in a straight line for 4.1 h at a constant speed of 95 km/h . What is its acceleration? Answer in units of m/s 2 .
Zanzabum

Acceleration is a change in speed, so if the car has a constant speed then it's acceleration is 0m/s^2.
