Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 5.7 m/s2 for 3.1 seconds. It then continues at a constant speed for 8.5 seconds, before applying the brakes such that the car's speed decreases uniformly coming to rest 203.88 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the blue car comes to a stop.
How fast is the blue car going 9 seconds after it starts?
What is the phase dierence between wavefronts originating from the two slits, at a point on the screen located +Π/10m from the zero'th order?
The bowling ball has a diameter of 20.6 {rm cm}, and the angle the stick makes with the horizontal is 30.0 {rm ^circ}. You may suppose there is no friction between the stick and the bowling ball, though friction with the floor must be taken into acco..
Jupiter is 23.10 m/s2. What is the ratio of your speed on Jupiter to your speed on Earth when you have dropped 45.0 m? Overlook the effects of air resistance and suppose that you start at rest.
A stunt pilot performs a circular dive of radius 715m. At the bottom of the dive pilot has a speed of 265 m/s which at that instant is increasing at a rate of 15 m/s2(along the direction of vector B) What total acceleration does the pilot have at ..
