An object is propelled along a straight-line path by a force. If the net force were doubled, the object's acceleration would be_

nikdorinn [45]

Answer:

double

Explanation:

According to the newton's second law

force = mass x acceleration

So, acceleration is directly proportional to the force.

As the force is doubles, the acceleration is also doubled.

Two pulleys are fastened together to form an integral unit. At a certain instant, the indicated belt tensions act on the unit an

tresset_1 [31]

Answer:

α = $21.6 rad/s^2$

Explanation:

Applying the equations of motion to determine angular acceleration of the unit,

The sum of moments about O is equal to the product of angular acceleration and moment of inertia

∑Mo = Io*α

Taking the anticlockwise direction as positive moment,

= ( -(1150) + (1400) ) * (0.5 / 2) + ( (475) - (650) ) * (0.3 / 2) - F = Io*α

= 36.5 - (2.5 N.m) = $(m*ko^2)$ *α

NOTE: moment of inertia of the pulleys in this instance = $(m*ko^2)$

Hence, 33.75 = $25 * (0.25)^2$ * α

Solving, α = $21.6 rad/s^2$
