Hey there!
A ball rolls 3 times. If she adds the three measurements and divides it by 3, it means that this is the average speed. The average speed is found by adding all measurements and dividing by the amount of numbers.
I hope this helps!
Answer:
Force exerted on the car = 4,000 N
Explanation:
Mass of the car (m) = 2000 kg
Acceleration(a) = 2 m/sec²
By Newton's second law of motion,
F (force) = m a
Putting the values of m and a
= 2000 x 2 = 4,000 N
Answer:
Kinetic energy does not stay the same at all heights
Explanation:
Well as the height and wind increase so does the kinetic energy it's like when you fall as you are about to hit the floor you speed increases
HOPE THIS HELPS YA :)
Answer:
Yep.
Explanation:
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. Gravity will pull the object down. So yes, gravity affects kinetic energy.
