Explanation:
Answer:
Explanation:
Given
mass of sled =26 kg
coefficient of static friction
coefficient of kinetic friction
In order to move sled from rest we need to provide a force greater than static friction which is given by
After Moving Sled kinetic friction comes in to play which is less than static friction
therefore minimum force to keep moving sledge at constant velocity is 18.34 N
Answer:
(a) 2.512 m
(b) 144 m
(c) 904.32 m
Explanation:
radius, r = 4.8 m
(a) for 30 degree
As we know that in 360 degree it rotates a complete round that means circumference.
In 360 degree, it rotates = 2 x π x r
in 30 degree, it rotates = 2 x π x r x 30 / 360
= 2 x 3.14 x 4.8 x 30 / 360
= 2.512 m
(b) for 30 rad
As we know that in one complete rotation, it rotates by 2π radian.
so,
for 2π radian it rotates = 2 x π x r
for 30 radian, it rotates = 2 x π x r x 30 / 2 π = 144 m
(c) For 30 rev
In one complete revolution, it travels = 2 x π x r
in 30 rev, it travels = 2 x π x r x 30 = 2 x 3.14 x 4.8 x 30 = 904.32 m
