Answer:
3.025 revolutions
Explanation:
To solve this question firstly we need to calculate the time t
Given the angular velocity and the angular acceleration
The time t = angular velocity/angular acceleration
Converting 50rpm to rad/s
= 50 × 2π /60
=1.67 rad/s
t = 1.67/0.46
t =3.63s
The wheel makes 50 revolutions in one minute
Therefore in 3.63s, it will make
3.63 × 50/60
= 181.5/60
=3.025 revolutions
Approximately 3 revolutions
So your finding acceleration first which is 30m/s divides by 6 seconds equals 5m/s^s and then multiply that by 1,400 kg and you have net force which is 7,000N
Vector is perpendicular to x axis or i component.
Hence i component is 0
j component is 63.5
