Answer: 6.47m/s
Explanation:
The tangential speed can be defined in terms of linear speed. The linear speed is the distance traveled with respect to time taken. The tangential speed is basically, the linear speed across a circular path.
The time taken for 1 revolution is, 1/3.33 = 0.30s
velocity of the wheel = d/t
Since d is not given, we find d by using formula for the circumference of a circle. 2πr. Thus, V = 2πr/t
V = 2π * 0.309 / 0.3
V = 1.94/0.3
V = 6.47m/s
The tangential speed of the tack is 6.47m/s
Answer:
Explanation:
Given:
Angular velocity, w = 3.33 times a second
= 1 rev in 3.33 s
w = 1/3.33
= 0.3 rev/s
Comverting from rev/s to rad/s;
0.3 rev/s × 2pi rad/1 rev
= 1.89 rad/s
Radius, r = 0.309 m
tangential velocity, v = w × r
= 1.89 × 0.309
= 0.583 m/s
