Sean is riding his bike (total mass of 82 kg) to school when a squirrel suddenly darts in front of him causing him to brake.
a) Draw a free body diagram for Sean and his bike as he is braking.
b) What is the net force in the FBD?
c) Calculate the value of the force of friction if the coefficient of kinetic friction is 0.70.
d) What is Sean's acceleration?

A train is traveling with a speed of 16.0 m/s relative to Earth. What is the velocity of the baseball relative to Earth
A dock worker loading crates on a ship finds that a 25 kg crate, initially at rest on a horizontal surface, requires a 90 N horizontal force to set it in motion. Find the coefficient of static friction and coefficient of kinetic friction
A 1000-kg car traveling with an x component of velocity of +20 m/s collides head-on with a 1500-kg light truck traveling with an x component of velocity of -10 m/s. what are the magnitudes of the final speeds of the car and truck
A car with a mass of 1.50x10^3 kg starts from rest and accelerates to a speed of 18.0 m/s in 12s. Assume that the force of resistance remains constant at 400-N all through this time. What is the average power developed by the car's engine?
a spherical gaussian surface is drawn inside a spherical object as shown. upon inspection no net charge exists within
Up where the ISS (International Space Station) orbits at 387 km, even though they are weightless there still is an acceleration due to gravity. Calculate its value and what it is in respect to 8g at the Earth's surface.
Determine the required concentration of the donor and the acceptor Impurities, assuming that all the impurities are ionized, I e., each donor gives one electron and each acceptor gives one hole.
