Calculate the torque and be sure to include units and sign. a force of 18.4 n is applied perpendicular to the end of a long level arm with length 97.8m causing a clockwise motion. what the torque?

The torque is 1799.52 N-m

Explanation:

Given that,

Force = 18.4 N

Length = 97.8 m

We calculate the torque,

Torque is the product of the force and perpendicular distance.

Where, F = force

l = length

Put the value into the formula

Hence, The torque is 1799.52 N-m

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
