An air hockey puck is sliding over an air-hockey table with an initial velocity of -10 m/s until it's hit by...that thing you hit the puck with in air hockey...and its velocity afterwards is 2 m/s. If the mass of the puck is 0.1 kg, then what is the impulse delivered to the air hockey puck? Write your answer in units of N's, but only write down the number part of your answer. 2 1.2 0.4 1.6

Problem An electric motor provides a constant torque of 12 N.m on a pivoting flywheel which has an inertia around the shaft of 3 kg.m2 and a friction constant of 3 kg.m2 / s. Motor it starts with silence. Zero tolerance is expressed in 2% to face value. 1. Calculate the total work done by the torque from rest until equilibrium is reached angular velocity! 2. Calculate kinetic energy when angular velocity equilibrium is reached! 3. Calculate the average power given by the motor from idle until it is reached equilibrium!

Express the torque of F, on ab, with respect of the axis ef, in terms of F, and Ly. Express the torque of F, on ed, with respect of the axis ef, in terms of F and L2. What is the total torque on the current loop with respect of axis ef, in terms of F, and L2? Calculate the numerical value of the total torque in Nm.  Express the torque of F, on ab, with respect of the axis ed, in terms of F, and Lz.

3. For the shift lever shown, the direction of a is equal to 15º. Determine the magnitude of the force P which has a 21 N.m clockwise moment about B. N counterclockwise / clockwise คําตอบ: P =.... B P 0.2 m- m→ 0.55 m

A ring, of mass 3.00 kg and radius 19.2 cm, can freely rotate about the axle as shown above. If the ring starts at its highest position and is given a small nudge, it will begin to rotate around the axle. What is the speed of the lowest point of the ring when the ring has reached its lowest position?

The following equation provides the relationship between the electrical frequency and the rotational speed of a generator; the standard for electrical frequency in Canada is 60 Hz. f = nm * P / 120 Where: f = Electrical frequency (Hz) nm = Rotor speed in revolutions per minute (rpm) P = Number of poles If a generator has 6 poles, what would be the rotor speed, nm, for a generator located in Canada? Select one:a. 1800 rpmb. 2400 rpmc. 1200 rpmd. 600 rpm
