Answer:
60000N
Explanation:
acceleration is change in velocity
a =(v-u)/t where a is acceleration u is initial velocity and v is final velocity
a = (0-60)/5 = -60/5= - 12m/s^2
here minus sign shows that body is decelerating and force is force of friction Now f = ma here f is force of friction m is mass and a is acceleration
f= 5000×- 12= -60000N
MINUS SIGN HERE SHOWS FORCE OF FRICTION
Hence force of friction is 60000N
Answer:
It's a quantitative observation because it includes numerical data.
Explanation:
please mark brainliest if im correct
If earth was not tilted on a axis, we wouldn't have any seasons. we wouldn't have seasons because the axis tilts us towards or away from the sun, and if you're tilted torwards the sun the sun you would have summer. if you're tilted away from the sun, you have winter. if there was no axis, the temperature would be the same all around the earth, so therefore we would not have seasons.
hopefully this helps
The type of star is the north star
<span>The answer is that, Mass, time, and length are
the quantities that would change considering the speed of light as the limit. In
Einstein's equations it depends on velocity as a fraction of the speed of light.
we can take example as,
Appeared length = rest length x </span><span>(1-u</span>²<span>)</span>⁽¹/²⁾
<span>in this u is the velocity as a fraction
of the speed of light. </span>
