Seasons because the tilt of the Earth's axis causes the sun to hit different spots with more or less light. So if the Northern part of the Earth is tilted away from the Sun, it's winter. But if it's tilted towards the sun, it's summer. Hope that helps!
Answer:
10.284 kgm/s
4.674545 kN
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
m = Mass of baselball
Impulse
Impulse of the baseball is 10.284 kgm/s
Impulse is also given by
The magnitude of the average force exerted by the bat on the ball is 4.674545 kN
Answer:
The time period of the empty car will be "1.00 s".
Explanation:
The given values in the question will be:
Mass,
m = 250 kg
Loaded car's time period will be:
T = 1.08 s
Shock absorbers compression,
x = 4 cm
or,
= 0.04 m
Now,
Weight of passengers will be:
⇒
The spring constant of shock absorbers will be:
⇒
As we know,
Time period,
On substituting the values, we get
(Total mass of car as well as its passengers)
Now,
The mass of the empty car will be:
⇒
hence,
The time period of empty car will be:
⇒
or,
