Josh is riding his skateboard down a ramp he kicks off and starts with a speed of 0.5 m/s after 1.5 seconds Josh reaches the bot
1 answer:
You might be interested in
initial velocity of the car given as
final velocity is given as
as we know that
now we can convert final speed into m/s
now acceleration is rate of change in velocity
so the acceleration of the car is 3 m/s^2
Answer:
Explanation:
Given
mass of ice cube
inclination
Spring constant
initial compression
Suppose Initially the cube is at the datum and it moves h height after release
So Elastic Potential Energy of Spring will convert to Potential Energy of cube
so final Potential Energy will be
Initial Potential Energy
B.Initially spring is at compression so energy associated with it is its Elastic Potential Energy i.e. 0.125 J
Final Energy
