A 1,652 kg car moving east at 12 m/s collides with a 1,526 kg car moving south at 15 m/s and the two cars stick together after the collision.
a) Find the velocity of the cars right after the collision?
b) Find how much kinetic energy was converted to another form of energy during the collision?
A line of positive charge is formed into a semicircle of radiusR. The charge per unit length along the semicircle isdescribed by the expressionλ=λ0/θcosθ. Calculate theelectric field at the center of the curvature.
a large fake cookie sliding on a horizontal surface is attached to one end of a horizontal spring with spring constant
If you lie on the ground at night with no cover, you get cold rather quickly. Much of this is due to energy loss by radiation. Estimate the net rate at which your body loses energy by radiation to the night sky under these conditions
A source delivers an AC voltage of the form ?v = 98.0 sin (80?t), where ?v is in volts and t is in seconds, to a capacitor. The maximum current in the circuit is 0.500 A. Find the rms voltage of the source
