Answer:
Explanation:
Distance is the product of speed and time.
The speed of the car is 75 kilometers per hour. It traveled for 5.5 hours.
Substitute the values into the formula.
Multiply. Note that the hours will cancel each other out.
The car travelled <u>412.5 kilometers.</u>
answer of both parts are attached below
mass = 4 kg
velocity = 5 m/s^2
<h3 /><h3>Orange truck:</h3>Mass= 2kg
Velocity = 7m/s^2
<h3 /><h3>Grey Car:</h3>mass = 6 kg
velocity = 4m/s^2
<h3 /><h3>Green Car:</h3>Mass = 8 kg
Velocity = 3 m/s^2
<h2>_____________________________________</h2><h2>SOLUTION:</h2>By the equation of kinetic energy,
K.E =
Where,
K.E is kinetic energy
m is mass
v is velocity
<h2>_____________________________________</h2><h3>Kinetic energy of Blue car:</h3>
Directly substitute the variables in the equation,
K.E =
Simplify the equation,
K.E = 50 J
<h2>_____________________________________</h2><h3>Kinetic Energy of Silver Car:</h3>
Directly substitude the variable in the equation,
K.E =
Simplify the equation,
K.E = 48J
<h2>_____________________________________</h2><h3>Kinetic Energy of Green Car:</h3><h3 />Substitute the variables in the equation,
K.E =
Simplify the Equation,
K.E = 36J
<h2>_____________________________________</h2><h3>Kinetic Energy of Orange Truck:</h3><h3 />Substitute the variable,
K.E =
Simplify the equation,
K.E = 49J
<h2>_____________________________________</h2>As you can see that the highest value of kinetic energy is of Blue SUV thus it will be out answer.
