Answer:
The final speed of the bicyclist is 15.44 m/s.
Explanation:
Given;
initial velocity, u = 0
time of motion, t = 4.8 s
distance covered, d = 37.0 m
The acceleration of the bicyclist is calculated as;
d = ut + ¹/₂at²
37 = 0 + ¹/₂(4.8)²a
37 = 11.52a
a = 37 / 11.5
a = 3.22 m/s²
The final speed of the bicyclist is given as;
v² = u² + 2ad
v² = 0 + 2(3.22)(37)
v² = 238.28
v = √238.28
v = 15.44 m/s
Therefore, the final speed of the bicyclist is 15.44 m/s.
I believe this is a true or false question. The answer is true. The reason we have seasons is because of the earths tilt. So without it, we would simply have a constant weather pattern. That's why it can get so cold around the North Pole, the tilt is most drastic there. So the real answer is that it depends on where you live. If you're on the equator, then no, not having a tilt won't impact climate much, but the further you are from the equator, the more change there would be.
Weight=mass x gravitational force
W=60 x 1/100 x 10
W=60 x 0.1
W=6N
Answer:
This is Newton’s third law (forces due to friction). There would be 15N being pushed back at Jane.
Explanation:
Newton’s third law states that for every action there is an equal and opposite reaction. So if Jane pushed with a force of 15N, 15N would be pushed back at her. Hope this helps! :)
