Explanation:
propagation means starting point, and waves travel from the starting point forward until something changes the direction of the waves. good luck!
Answer:
6 s
Explanation:
First of all, we calculate the acceleration of the car in the initial situation, using the equation
where
v = 30 is the final velocity of the car
u = 0 is the initial velocity
t = 12 s is the time taken
Substituting,
So, this is the acceleration of the car.
In the second situation, the car velocity goes from
u = 0
to
v = 15 m/s
So, we can use again the same equation to find t, the time it takes for the velocity of the car to change between these values:
Answer:
Yes
Explanation:
Kinetic energy is K.E1/2mv2 so that means it is directly proportional to mass and velocity.
