acceleration = Velocity changes ÷ time of the velocity changes
4 m/s^2 =
4 × 10^(-3) × 3600 km / h =
4 × 3.6 =
14.4 km / h
Thus :
14.4 = V(2) - V(1) / t(2) - t(1)
14.4 = V(2) - 20 / 10
Multiply both sides by 10
10 × 14.4 = 10 × ( V(2) - 20 ) / 10
144 = V(2) - 20
Add both sides 20
144 + 20 = V(2) - 20 + 20
V(2) = 164 Km/h
Thus the final velocity after 10 seconds is 164 Km/h .
The dimensions needed for this is <span>55 cm x 100 cm x 80 cm.</span>
Let k be the spring constant. Then you have
188=k*21.8
k=188/21.8=8.62,
In the second part you use
m g= k x
x=m g/k= 38/8.62=4.4cm
4.4 cm is the answer
If youre talking about plane mirrors: virtual, upright, left-right reversed, same distance from the mirror as the objects distance, and the same size as the object.
Questions in this category that include the words "This graphic shows..."
or some such, frequently fail to include any graphic. When no graphic is
included, it must follow as the night follows the day that no physics is pictured
in the scene. Inertia is a very popular subject, often appearing in scenes
where physics is pictured. Sadly, however, in an environment that is totally
devoid of graphics, projectiles and the inertia they carry are seldom to be found.
