An object has a mass of 4kg and experiences a gravitational force of 40N. If the object experiences no other forces, what will its acceleration be? What do you need to FIND?
Force Mass Or Acceleration

What do you KNOW? (For the KNOW step you will need to identify which variable is being described by each value in the problem.)

What is the ANSWER?

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
