Answer:
Distance = 0.35 miles
Displacement = 0 miles
Explanation:
The distance covered Ryan is the sum of the diatances moved from his house and then back to his house. According to the question, after covering 0.35 miles, Ryan arrived back in his house. Hence, distance covered by Ryan is 0.35 miles.
Displacement refers to overall change in position of an object from a certain starting position.
In the scenario above, Ryan's Displacement from is house will be zero, since ;
Starting position is his house and his final position is his house.
Hence, change in position or distance from his house = 0 miles
Answer:
Explanation:
Uh so I don't know the concept of your question but the inertia I know is the Newton Law version. Inertia is the tendency of a object to remain rest or in motion. The object will move or stop at a constant speed until affected by a sudden impacted change.
Answer:
Explanation:
v = u +at
u = 0
a = 2.3 m /s²
t = 20 s
v = 2.3 x 20
= 46 m /s
Distance covered under acceleration of 2.3 m/s²
s = ut + 1/2 at²
= 0 + .5 x 2.3 x 20²
= 460 m
After that it moves under free fall ie g acts on it downwards .
v² = u² - 2gh , h is height moved by it under free fall
0 = 46² - 2 x 9.8 h
h = 107.96 m
Total height attained
= 460 + 107.96
= 567.96 m
b ) At its highest point ,it stops so its velocity = 0
c ) rocket's acceleration at its highest point = g = 9.8 downwards .
At highest point , it is undergoing free fall so its acceleration = g
