Answer:
because it is an ice that is why it melt
Answer:
10.99 m
Explanation:
m = mass of the block = 0.245 kg
k = spring constant of the vertical spring = 4975 N/m
x = compression of the spring = 0.103 m
h = height to which the block rise
Using conservation of energy
Potential energy gained by the block = Spring potential energy
mgh = (0.5) k x²
(0.245) (9.8) h = (0.5) (4975) (0.103)²
h = 10.99 m
Given constant acceleration, we can get the final position of an object in terms of both its initial velocity and its acceleration using one of the equations of motion.
The equation that we will use is:
Xf = Xi + Vi*t + (1/2)*a*t^2
where:
Xf is the final position of the object
Xi is the initial position of the object
Vi is the initial velocity of the object
t is the time
a is the constant given acceleration
Answer:
27 Joules.
Explanation:
use the formula for kinetic energy:
KE = 1/2mv^2
Trailer Hitches are categorized into a five classes I, II, III, IV and V. Trailer ratings are based on the total weight of the trailer or boat.
Class I trailer hitch is best suited for a boat and its equipment weighing less than 2,000 pounds and class II trailer <span>hitch is best suited for a boat and its equipment weighing 2,000 pounds or greater up to 3500 pounds. Class III, IV and V have their own range.
