A. Belts
Cuz you need shoes, the shirt and maybe the socks.
Answer:
1) A:1, B:1, C:1
2) A:1, B:1, C:1
3) B:1, C:2, A:3
Explanation:
1)
a = , where V - linear speed.
R - radius of ferris wheel.
These values are constant, so at any position centripetal acceleration will be the same.
2)
F = ma = , where a - centripetal acceleration.
V - linear speed.
R - radius of ferris wheel.
These values are constant, so at any position centripetal force will be the same.
3)
So, at bottom point normal force is maximume, at top point normal force is minimum.
B:1, C:2, A:3 (bottom: Greatest, midheight: Second greatest, top: Third greatest)
Answer:
60N
Explanation:
Given parameters:
Combined mass = 50kg
Acceleration = 1.2m/s²
Unknown:
Force to propel = ?
Solution:
From Newton's second law of motion, we know that;
Force = mass x acceleration
So;
Force = 50 x 1.2 = 60N
