Answer:
A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newton (N). Force is represented by the symbol F. The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time.
Other units: dyne, pound-force, poundal, kip, kilopond
SI unit: newton (N)
Common symbols: F→, F, F
The answer is B. natural gas
Depends on the situation. It could be something like potential energy of a compressed or stretched spring.
Answer:
15.03 m
Explanation:
Given:
mass of the block, m = 7.25 kg
Angle, Θ = 28.5°
Initial speed of the block, v₀ = 15 m/s
let the distance traveled by the block be 's'
Now, applying the work energy theorem,
we have

on substituting the values in the above equation, we get

or

or

s = 15.03 m
Hence, the block will travel 15.03 m up the ramp
Answer:
4.00m
Explanation:
at that instant where it is dropped all the mechanical energy is gpe which is 71.9
and the formula for gpe = mass (1.80) * height * gravitational field strength (i'm using 10 m/s2)
height of football stadium
= 71.9/[(1.80)(10)]
= 71.9/18.0
= 3.99444..
= 4.00 (3 sf)
