Answer:
(a) 7 m/s
(b) 931 rad/s
(c) 0.716 s
Explanation:
Gravity would be exerting on the 2 masses


Since heavier, mass 1 (M) would be the one pulling down, while mass 2 is being pulled up.
So the net force on mass 1 is

This force would generate torque on the solid pulley

We can also calculate the pulley moments of inertia, with it being solid

From there we can calculate the angular acceleration of the pulley, which generates the entire system motion

Since the system is moved by a distance of d = 2.5m, the pulley would have turn an angle of

(c)The time it takes to get to this distance is



(b)The final angular speed of the disk is

(a) And so the perimeter speed of the pulley, which is also speed of mass 1 when it comes to d = 2.5 m is

When a swimmer pushes threw water to swim they are propelled forward because of the water resistance against the hand and feet.
You get circular motion, where the acceleration is pointing towards the center of the circle, as long as they are constant, and not fluctuating.
Answer:
The sport utility vehicle was traveling at V2= 11.5 m/s.
Explanation:
m1= 1090 kg
V1= 30.4 m/s
m2= 2880 kg
V2= ?
m1*V1 = m2*V2
V2= (m1*V1)/m2
V2= 11.5 m/s
The answer is 789.25 which you’d subtract 2011.25-122.2 I think sry if I’m wrong
