Newton`s Laws and The Force
... 19. A pair of fuzzy dice is hanging by a string from your rearview mirror. While you accelerate from a stoplight to 40 m/s (in 8 seconds), what angle does the string make with the vertical? To solve this find (a) the acceleration of the car/dice. (b) Now draw a FBD, and make a force chart etc. (Ar ...

... The acceleration of an object is in the same direction as the net force. The formula can be arranged to show how much force must be applied to an object to get it to accelerate at a certain rate. Net force = Mass × Acceleration or F = ma For example, you apply a net force to a ball when you throw it ...

... Integrating this equation gives y(t) = (39g/4)(t + 10e–t/10 + C). Using the initial condition y(0) = 0 gives that forces C = –10. So for our equation of motion we get y(t) = (39g/4)(t + 10e–t/10 – 10). Setting the formula for velocity equal to 70 and solving for t: [(39× 9.81)/4](1 – e–t/10) = 70 1 ...
