Friction causes resistance against a moving object. It can cause an object to slow down, or stop when there’s enough friction…. I hope this helps
The flowers attracts insects, birds, and small animals. They also attract humans, who admire the
Solve for the time it will take to complete a revolution. That is,
0.510 s / 440 revolutions = 51/44000 s
The frequency in Hertz is the reciprocal of this value thus the frequency is approximately equal to 862.75 Hz.
Angular velocity expressed in radians/second
(440 rev / 0.510 s) x (2π rad / 1 rev) = 5420.787 rad/s
The period is the reciprocal of frequency which is approximately equal to 1.16x10^-3 s.
Answer:
11.27 m /s
2.98 m / s.
Explanation:
80 km / h = 22.22 m /s
Tanq = 4 / 100
Sinq = .0399
Deceleration acting on inclined plane = g sinq
= 9.8 x .0399
= .3910
Initial speed u = 22.22 m/s
acceleration = - .3910 ms⁻²
v = u - a t
= 22.22 - .3910 x 28
= 22.22 - 10.95
= 11.27 m /s
b ) v² = u² - 2 a s
v² = ( 22.22) ² - 2 x .3910 x 620
= 493.7284 - 484.84
= 8.8884
v = 2.98 m / s.
