Q. A car starts from rest on a curve with a radius of 110 and accelerates at 0.500 . How many revolutions will the car have gone through when the magnitude of its total acceleration is 3.50 ?
Q. A subway train accelerates from rest at one station at a rate of 1.30 m/s^2 for half the distance to the next station, then decelerates at this same rate for the second half of the distance. If the stations are 4200m apart find the time of travel (in seconds) between the two stations.
How much energy is delivered to the battery. What is the velocity v of the smaller fish before lunch.
An airplane is flying with the velocity of 85.0 m/s at an angle of 20.0 degrees above the horizontal. When the plane is a distance 107 m directly above the dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far..
While on vacation you rent a moped and go cruising around a tropical island. If you take a 10.0 degree banked curve with a radius of 15.0 meters at 12.0 m/s, what is the minimum coefficient of static friction between your tires and the road to keep t..
When the plunger is pushed, contents of the syringe are forced throughout a hollow needle (also of circular cross-If a 4.0 N force is applied to plunger and diameters of the plunger and the needle are 1.20 cm and 2.50 mm, correspondingly, what force ..
A 60 kg woman stands on a very light, rigid board that rests on the bathroom scale at each end. She is 1.5m away from one side and 0.5 m from the other.
A cord is wrapped around the rim of a solid uniform wheel 0.300 in radius and of mass 7.80 . A steady horizontal pull of 40.0 to the right is exerted on cord, pulling it off tangentially from the wheel. The wheel is mounted on frictionless bearing..

Two lenses that are L = 42 cm apart are used to form an image, as shown in figure. Find the distance from lens and magnification of the image.
A wooden block weighing 7 N is at rest on top of a wooden desk. The coefficient of static friction between the block and the desk is 0.41. Find out the minimum horizontal force required to move the block if the following occurs.
At a large business, employees must report to work at 7:30 A.M. The arrival times of employees is approximately symmetric and mound-shaped with mean 7:22 A.M. and standard deviation 4 minutes.
In fact, the increased normal force at these large angles makes force of friction too large to move the lawnmower at all.
