Answer:
Explanation:
Torque created by force 3.34N
= 3.34 x 1.39 = 4.64 N.m
This torque is acting in clockwise direction .
Torque created by force 8.52 N
8.52 x .48
= 4.09 N.m
The force of 8.52 N is acting downward . It may turn the cylinder in clockwise or anticlockwise direction . So we shall consider both the possibilities.
If it rotates the cylinder in clockwise direction
Total torque = 4.64 + 4.09
= 8.73 Nm
If it rotates the cylinder in anticlockwise direction
Total torque = 4.64 - 4.09
= .55 Nm
Net torque will be in clockwise direction.

<h2>The velocity of car was m m/s </h2>
Explanation:
When the car skids , its centripetal force is provided by frictional force .
Here centripetal force F = 
here v is the velocity of car and r is the radius of the curve .
The frictional force f = μ R
here μ is the coefficient of kinetic friction and R is normal reaction
Thus f = m g
On horizontal road R = mg
Thus F = f at the time of skid .
Thus v = 
=
= 9 m/s
Answer:
33.68 N
Explanation:
Data
W= 32J
d- 0.95m
F= ?
W=Fd
They are asking for the magnitude which is the force, so you need to solve for force.
F=W/d
= 32J/ 0.95m
= 33.68 N
