Increasing mass increases kinetic energy. This can be seen in the equation KE = 1/2 (m) (v)^2

Answer:
166 cm
Explanation:
Given :
d1 =109cm
M1= 45kg
M2=29000g = 29 kg
As we know that Newton second law
Here M1= 45kg
and acceleration=
Therefore
M2=29000g = 29 kg
Similarly
Now we using the Principal of moments
~ d2=166 cm
Answer:
<u><em>3 hours</em></u>
Explanation:
If the car takes 2 hours to go 40 miles, then the car can go 20 miles in 1 hour. Since the car is going 60 miles, it will take 3 hours.
Hope that makes sense :)
Answer:
100 N
Explanation:
The following data were obtained from the question:
Mass (m) = 2 Kg
Velocity (v) = 5 m/s
Radius (r) = 50 cm
Force (F) =.?
Next, we shall convert 50 cm to metre (m). This can be obtained as follow:
100 cm = 1 m
Therefore,
50 cm = 50 cm × 1 m / 100 cm
50 cm = 0.5 m
Therefore, 50 cm is equivalent to 0.5 m.
Finally, we shall determine the magnitude of the net force on the ball by using the following formula:
F = mv²/r
Mass (m) = 2 Kg
Velocity (v) = 5 m/s
Radius (r) = 0.5 m
Force (F) =.?
F = mv²/r
F = 2 × 5²/ 0.5
F = 2 × 25/ 0.5
F = 50 / 0.5
F = 100 N
Therefore, the magnitude of the net force on the ball is 100 N.
Answer:
Herbivores have special teeth and digestive enzymes to digest their food while carnivores do not have digestive enzymes
