Answer:
The acceleration of a car would be:
m/s²
Explanation:
Given
Initial velocity =
m/s
Final velocity =
m/s
Time elapsed =
s
To determine
We need to determine the acceleration of a car.
We know that acceleration is basically the rate of change in velocity over time.
Thus,
We can determine the acceleration using the formula

where
is the acceleration
is the initial velocity
is the final velocity
is time elapsed
now substituting the values
,
, and
in the formula



m/s²
Therefore, the acceleration of a car would be:
m/s²
It is a seismograph that would be most useful.
The solution to the problem is as follows:
Normal force is m*g plus 240 N*sin30.
<span>30 kg*9.8 m/s^2 + 240 N*sin30 = 414 N
