Answer:
Step-by-step explanation:
Given Equation:
Actually the given equation is the 2nd equation of motion
i.e. 
where 
because the astronaut jumps on the earth
and initial velocity 
to find time 
, put the given value of 
in the given equation, we get
it will take to reach the ground if he jumps on the Earth
Answer:
Mm I didn't get the picture
Answer:
Step-by-step explanation:
v=Q-P
v=(5,1,0)
u=v/(magnitude of v)=(5,1,0)/(\sqrt{5^2+1^2+0^2)
u=(5/5.09,1/5.09,0)
v=Q-P
v=(1,1,0)
u=v/(magnitude of v)=(1,1,0)/(\sqrt{1^2+1^2+0^2)
u=(1/
,1/,0)
Answer:
x8
Step-by-step explanation: bacause if you see and look really close
The scatter plot has been attached
Answer:
Options C, D & E are true
Step-by-step explanation:
Option A is wrong because from the scatter plot, only four athletes were faster in the second race than in the first one.
Option B is wrong because only 1 athlete had his second race time differing from the first race time by exactly 2 seconds.
Option C is true because exactly 9 of the times for the first race were at least 16 seconds
Option D is true because there are exactly 3 athletes who had the same time in both races
Option E is true because 8 of the times for the second race were less than 17 seconds
