Answer:
The slope of the position time graph gives the velocity.
Explanation:
The slope of the position time graph gives the value of velocity.
In first graph,
The slope is constant in both the parts but positive . So the velocity is also constant and positive for both the parts. and more than the second part, so the initial velocity is more than the final velocity.
In the second graph,
The slope is constant in both the parts but negative. So, the velocity is constant but negative for both the parts. Initial velocity is more negative than the final velocity.
Answer:
45 degrees
Explanation:
The textbooks say that the maximum range for projectile motion (with no air resistance) is 45 degrees.
You need more information--with what you wrote, the 0.08 kg car travelling at 1.00 m/s would have the same effect since both cars would have equal momentum, so it would need to be travelling >1.00 m/s to break the egg, assuming what you wrote is the complete problem
Answer:
C. 1.43 m/s
Explanation:
Velocity = displacement / time
v = (1 m − -9 m) / 7 s
v = 1.43 m/s
