When s =0 the spring of the firing mechanism is unstretched if the arm is pulled back such that s =100mm and released determine the maximum angle theta the ball will travel without leaving the circular track

Avery hard rubber ball (m = 0.5 kg) is falling vertically at 4 m/s just before it bounces on the floor. the ball rebounds back at essentially the same speed. if the collision with the floor lasts 0.05 s, what is the average force exerted by the floor on the ball?

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will
