Answer:
Length/time
Explanation:
As in the definition...Velocity is the rate of change of displacement...so hence
Velocity = Displacement/Time...where Displacement is length
Velocity = Length/Time
The coefficient of static friction between the puck and the surface.
In fact, that coefficient describes exactly how "hard" it is to cause the puck to start moving, if it starts from an idle condition.
Answer:
C) 100N
Explanation:
Formula for calculating the Weight of an object is expressed as;
Weight = mass × acceleration due to gravity
Given
Mass of the object = 10kg
Acceleration due to gravity = 9.81m/s²
Substitute into the formula above
Weight = 10×9.81
Weight = 98.1N
Hence the approximate weight of the object is 100N
Answer:
170 N
Explanation:
F=pressure(pa) ÷ area(m^2)
=100.000 ÷ 0,0017
=<em><u>170</u></em><em><u> </u></em><em><u>N</u></em>
u = 0.077
Explanation:
Work done by friction is
Wf = ∆KE + ∆PE
-umgx = ∆KE,. ∆PE =0 (level ice surface)
-umgx = KEf - KEi = -(1/2)mv^2
Solving for u,
u = v^2/2gx
= (12 m/s)^2/2(9.8 m/s^2)(95 m)
= 0.077
