You find it takes 220 n of horizontal force to move an unloaded pickup truck along a level road at a speed of 2.4 m/s. you then

load up the pickup and pump up its tires so that its total weight increases by 42% while the coefficient of rolling friction decreases by 19%.

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

A golf ball traveling 3m/s to the right collides in a head-on collision with a stationary bowling ball in a friction-free enviro
Vladimir79 [104]

Answer: equal to 3 m/s

Explanation:

Speed of golf ball will be equal to 3 m/s because in Perfect Elastic Collision Energy is conserved .

So speed of golf ball will be same in order to Satisfy

Initial Kinetic Energy =Final Kinetic Energy

Considering Bowling ball remains at rest after collision other wise some energy will also be acquired by bowling ball which automatically decreases the amount of Kinetic Energy of golf ball resulting its speed to decrease by some extent.

What are some changes that can be caused. By sound energy
aleksley [76]

Answer:

Hearing loss due to sound energy damaging the nerve cells in the inner ear. Many animals behavior is influenced by sound energy. They learn to associate events with sounds, so they run when something crunches in the dry grass (might be a coyote), but won't be bothered by the sound of a waterfall. Mood is affected by sound energy. A wine glass can break with sound energy, if the frequency matches the resonant frequency of the wine glass and the amplitude is great enough (one Mythbusters show featured a professional singer who broke a wine glass with his voice without any amplification).

Sound energy causes the particles in the medium it is traveling through to vibrate.

Unlike sound electromagnetic waves can travel trough empty space

hope these different answers help
