Water on the kitchen floor at home is considered a safety hazard.

A motorcycle at a stoplight takes 5.22 seconds to accelerate to a speed of 33.0 m/s after the light turns green. What is the average acceleration of the motorcycle?

The half-life of an isotope is 100 years. Use this information to determine the differential equation that describes the mass as a function of time. In other words m' = km where k is a constant and m (t) is the mass after t years.

An air-track glider undergoes a perfectly inelastic collision with an identical glider that is initially at rest. what fraction of the first glider's initial kinetic energy is transformed into thermal energy in this collision?

Two atoms that are isotopes of one another must have a different number of what? electrons neutrons protons all particles

How can you use the newton's second law to find force?

Now that we know the velocity of the cart before the collision is 1.80m/s, let's use this to determine the linear momentum and kinetic energy of the disk-cart system before the collision. The mass of the cart is 23.5kg. The mass of the disk is 11.
