You find yourself stuck in outerspace with nothing but your physics book and spacesuit. You have a mass of 108kg in your suit and your physics book has a mass of 3.7 kg. In order to make it back to your stationary spaceship before running out of air you must move at .29 m/s. How fast in m/s do you have to throw your physics book to achieve the speed
A physics student, in a stationary elevator, places a 240.0 g mass on an electronic balance. The student hits the elevator button and it begins to move upwards. While the elevator is moving, the student records this information Time = 0 to 3.0 sec the balance reads 278 grams Time = 3.0 - 12 sec the balance reads 240. grams Time = 12.0 to 15.0 sec the balance reads 192 gram How far up (in meters) did the elevator travel? Consider: UP to be (+), DOWN to be (-) and g =9.8 m/s2 . ROUND YOUR ANSWER TO A WHOLE NUMBER of meters (no decimal places) HINT: This problem requires finding THREE different displacements and adding them up! 2nd HINT: You will need to (A) use your equations of motion or (B) make a v-t graph to find those displacements!

A car (mass 1000 kg) is traveling at 60 mph (26.82 m/s) when the driver notices a cat 50 m ahead in the road. Wanting to save the feline's life, the driver slams on the brakes and comes to a stop 2 m in front of the cat. What was the car's acceleration as it was braking?
An object has a velocity (4.69 m/s)i + (-4.4 m/s)j + (4.73 m/s)k. In a time of 5.5 s its velocity becomes (-2.22 m/s)i + (0.00 m/s)j + (4.73 m/s)k. 1) If the mass of the object is 3.31 kg, what is the magnitude of the net force on the object, in N, during the 5.5 s? Assume the acceleration is constant.
5. What is the momentum (as a function of time) of a 5.0-kg particle moving with a velocity (v¯ (t) = 2.0i + 4.0tj) m/s? What is the net force acting on this particle?
