Answer:
Explanation:
Consider downward displacement first .
downward displacement h = 38 m .
downward acceleration = g
downward initial velocity u = 0
h = ut + 1/2 g t ²
38 = 0 + 9.8 t ²
t = 1.97 s
During this period , there will be horizontal displacement with initial velocity u = 10 m /s and acceleration a = 1.6 m /s²
s = ut + 1/2 a t²
= 10 x 1.97 + .5 x 1.6 x 1.97²
= 19.7 + 3.10
= 22.8 m
Answer:
Las propiedades físicas, como la dureza y el punto de ebullición, y los cambios físicos, como la fusión o la congelación, no implican un cambio en la composición de la materia.
Explanation:Creo que es correcta
This is the substance(s) formed in a chemical reaction. is called the products
Answer:
distance = 32 kilometers
displacement = 0 kilometers
Explanation:
they traveled 15 km to and back which would mean the distance they traveled is 32 km. but the displacement would still be 0 because their starting and ending points are the same.
