If a 500.0g cart had its velocity change from 1.65 m/s to 1.23 m/s over a period of 2.50 seconds.
A) Calculate and record the force acting.
B) What provided the force?
A baseball is thrown horizontally at the catcher, who is 60.0 ft away. It is thrown with a velocity of 87.5 mph. How far does the baseball fall during this pitch.
A mass of 0.5 kg is suspended from a spring, which stretches by 8 cm. The support from which the spring is suspended is set into sinusoidal motion. At what frequehcy would you expect resonant behavior?
A magnetic field near the ceiling points up and is decreasing. Looking up at the ceiling, does non-Coulomb electric field curl clockwise or counter-clockwise.
A 11 g bullet is fired horizontally into a 109 g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 142 N/m. The bullet becomes embedded in the block.
