AP Physics B Test 1



Question 1: A motorbike traveling along a straight road increases its speed from v1 = 20m/s to v2 = 40m/s in 5 seconds. If the acceleration is constant, what is the distance traveled during this time?









Question 2: The motion of a automobile is shown as a function of time in the graph below.

The distance traveled from point A(t = 1s) to point B(t = 4s) is:








Question 3:


A block is pushed across a horizontal surface by the forces F1 and F2 shown. If the block moves with an acceleration of 2m/s2, F1 = 15N, F2 = 10N and M = 2.5kg, which of the following is an approximation of the coefficient of kinetic friction between the block and the surface?









Question 4:



Two blocks of masses m1 and m2 slide down frictionless inclined planes, both dropping the vertical distance h. If m1 = 2m2, block 1 slides from A to B in t1 seconds and block 2 slides from C to B in t2 seconds, then:









Question 5:



What is the current in the 2 Ohms resistor while the switch S1 is open?









Question 6:



What is the voltage across the 1μ capacitor when the switch S1 is closed and C is fully charged?
