Kinetic friction for the truck is given by:
F = μ*N = μ*m*g
μ coefficient of friction
m mass of the truck
g gravitational constant = 9.81
Answer:
Kinetic Energy = 36 Joules
Explanation:
Given =
Mass = 2kg
Velocity = 6m/s
Solution =
Kinetic Energy = 1/2 × mv²
Kinetic Energy = 1/2 × 2 × 6 × 6
Kinetic Energy = 36 Joules
Answer:
Area under a curve can be estimated via block counting, calculated with simple geometry if the velocity has constant accelerations, or calculated by integration if the velocity can be described by a mathematical equations.
The area under a velocity time curve will be the product of velocity and time which equals displacement.
Answer:
The answer is D
Explanation:
Because the car is accelerating (moving) south at a speed of 45. Hope this helps for you. :)
The greater the energy, the larger the frequency and the shorter (smaller) the wavelength. Given the relationship between wavelength and frequency — the higher the frequency, the shorter the wavelength — it follows that short wavelengths are more energetic than long wavelengths.
