A clay ball (mass = 0.25kg) has a rightward momentum of +1.75 kg-m/s. A second clay ball (mass = 0.25 kg) has a leftward momentum of -1.75 kg. m/s. The two collide, stick together, and come to a complete stop
after the collision.

Me to solve all the questions on the sheet attached

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
