Kinetic energy is energy possess by an object due to it motion.
Mass 1; m = 500 Kg Velocity 1; V = 40 m/s
Mass 2; m = 1000 Kg Velocity 2; V = 20 m/s
Formula: K.E = 1/2mv²
For Mass 1 K.E = 1/2(500 Kg)(40 m/s)² = 400, 000 J
For Mass 2 K.E = 1/2(1000 Kg)(20 m/s)² = 200,000 J
This solution shows that a larger velocity will have a greater kinetic energy.
Answer:20 mph
Explanation:
Given
distance between college to Tyrone=20 miles
Given professor drives with a velocity of 60 mph
he returns to college after reaching tyrone and then again drive to tyrone.
so his net displacement is 20 miles
time taken to cover 20 miles is 
hr
average velocity
Answer:
D
Explanation:
Beacuse the force got to the bottem first Meaning the andswer is D
Answer:
1,3
Explanation:
As the acceleration is -10m/s^2 , that means deceleration is occurring. That means, the object is slowing down.
v=u-at
or, 0=80-10t
or, t=8 seconds
So, the object will stop in 8 seconds.
So, the correct answers are 1 and 3.
Hope, this helps you.
