Answer:
Driving in a straight line at 60 miles per hour
Explanation:
In the first case there's an acceleration that modifies the direction of the movement.
In the second case there's a lineal acceleration that increases the speed of the car.
in the third case there's a negative acceleration that reduces the speed of the car.
On the third case the speed is constant so the acceleration is 0 mi/s^2
 
        
             
        
        
        
Answer:
Explanation:
F=ma
F=10N
A=v-u upon t
=1.5-0 upon 3
=0.5m per second squared
Then do force divided by. Accelaration and multiply by gravity.

The minimum velocity of the Salmon jumping at the given angle is 12.3 m/s.
The given parameters;
- height of the waterfall, h = 0.432 m
- distance of the Salmon from the waterfall, s = 3.17 m
- angle of projection of the Salmon, = 30.8º
The time of motion to fall from 0.432 m is calculated as;

The minimum velocity of the Salmon jumping at the given angle is calculated as;

Thus, the minimum velocity of the Salmon jumping at the given angle is 12.3 m/s.

For a 50 kg person receives an absorbed dose of gamma radiation of 20 millirads,  the total energy absorbed is mathematically given as
E=0.1457J
<h3>What is the total energy absorbed?</h3>
Generally, the equation for the total energy absorbed  is mathematically given as
E=mass*gamma radiation
Therefore
E=50*20*19^{-3}
E=0.1457J
In conclusion,  the total energy absorbed
E=0.1457J
