During a gust of wind, the blades of the windmill are given an angular acceleration of α=(0.2 θ) rad/s2, where θ is measured in radians. if initially the blades have an angular velocity of 5 rad/s, determine the speed of point p located at the tip of one of the blades just after the blade has turned two revolutions.

7.5 rad/s

Explanation:

= angular acceleration = (0.2) θ

Angular acceleration is given as

Integrating both side

w = 7.5 rad/s

a skateboard rolling across the street - apex

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
