Answer:
588 J
Explanation:
PE (potential energy) = (mass) x (gravity) x (height)
mass = 12 kg
gravity = 9.8m/s^2
height = 5 m
PE = (12) x (9.8) x (5) = 588 J (Joules)
Complete Question
A small block is released from rest at the top of a frictionless incline. The distance from the top of the incline to the bottom, measured along the incline, is 3.40 m. The vertical distance from the top of the incline to the bottom is 1.09 m. If , what is the acceleration of the block as it slides down the incline plane
Answer:
The acceleration is
Explanation:
From the question we are told that
The distance from top to bottom of the inclined plane measured along the incline is
The distance from top to bottom of the inclined plane measured along the vertical axis is
According to the SOHCAHTOA rule
=>
substituting values
=>
T
The acceleration of a block on a frictionless inclined plane is mathematically represented as
substituting values
A spaceship on its way to another planet is traveling at a speed of 4200 miles per hour .This in units of millimeters per second will be 1877.568 m/s
Unit refers to the quantity of a constant magnitude, used to measure the magnitudes of other quantities of an identical type
1 mph = 0.44704 m/s
hence , 4200 mph = 0.44704 * 4200 = 1877.568 m/s
