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
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,

From the information provided we say that the distance between the cretas is 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




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



Answer:
Explanation:
using Elastic potential energy stored in a spring
It's the distance between the middle of the lens to the focus.
Acceleration is a change in speed, so if the car has a constant speed then it's acceleration is 0m/s^2.
