Answer:
Explanation:
average velocity is 41.6/1.89 = 22.0 m/s
initial velocity u is
22.0 = (u + u - 9.81(1.89))/2
44.0 = 2u - 18.5
62.56 = 2u
u = 31.3 m/s
max height is
v² = u² + 2as
s = (v² - u²) / 2a
s = (0² - 31.3²) / (2(-9.81)) = 49.9 m
49.9 = 41.6 = 8.27 m higher

Answer:t=0.81 s
Explanation:
Given
Penguin slides down with constant velocity of 3.57 m/s
as the Penguin Slides with constant velocity therefore 
is zero on Penguin
friction Force
coefficient of Kinetic friction
after reaching on floor final velocity of penguin will be zero after time t
thus
here 
(deceleration)
Answer:
Number of Significant Figures: 2
The Significant Figures are 3 6
Explanation:
= 3.60 × 102
(scientific notation)
= 3.60e2
(scientific e notation)
= 360 × 100
(engineering notation)
(one)
= 360
(real number)
Answer:
There's a video called Drawing Position vs Time Graphs made by MrDGenova that may help you, it's only three minutes long.
