physics: BOB or DRWLS follow up question
What average force is required to stop an 1100-kg car in 8.0 s if it is traveling at 95 km/h? i understand what you both did, but why can't you use the V = Vo + at equation and solve for acceleration there and use that in the EF = ma equation?

A pendulum is 0.9 m long and the bob has a mass of 1.0 kg. At the bottom of its swing, the bob's speed is 1.5 m/s. What is the tension in the string at the bottom of the swing?

A 250-gram pendulum bob is initially constrained at a 53 degree angle by two strings. When the horizontal string is cut the pendulum begins to swing. As the pendulum bob passes through its equilibrium position, what will be its velocity?

I don't no what I must do here: You observed something strenge. You noticed that your pet plant Bob is leaning toward the window in your room. He has been growing toward the window for some time and you wonder why he is doing that. 1.What process will you use to figure out why...
