It is B. if i'm not mistaking
Im pretty sure it’s 25,100 J because i had seen the same question a few times with this answer, hope it helps!
I’m guessing b because hydrogen is in your room and maybe eliminate to o but it also can be D
my final is: B!
Answer:
C) 50 m/s
Explanation:
With the given information we can calculate the acceleration using the force and mass of the box.
Newton's 2nd Law: F = ma
- 5 N = 1 kg * a
- a = 5 m/s²
List out known variables:
- v₀ = 0 m/s
- a = 5 m/s²
- v = ?
- Δx = 250 m
Looking at the constant acceleration kinematic equations, we see that this one contains all four variables:
Substitute known values into the equation and solve for v.
- v² = (0)² + 2(5)(250)
- v² = 2500
- v = 50 m/s
The final velocity of the box is C) 50 m/s.
Answer:
True
Explanation:
A sled sliding across snow or ice. Skis sliding against snow. A person sliding down a slide is an example of sliding friction. A coaster sliding against a table. Two cards in a deck sliding against each other. All of these are examples of sliding friction.
Hope this helps! :)
