Q. A motorcycle officer hidden at an intersection observes a car driven by an oblivious driver who ignores a stop sign and continues through the intersection at constant speed. The police officer takes off in pursuit 1.78 s after the car has passed the stop sign. She accelerates at 4.5 m/s2 until her speed is 103 km/h, and then continues at this speed until she catches the car. At that instant, the car is 1.2 km from the intersection.
(a) How long did it take for the officer to catch up to the car?
(b) How fast was the car traveling?
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..
A person who weighs 68 kg steps onto a spring scale in the bathroom, and spring compresses by 0.79cm. (a) what is the spring constant? (b) What is the weight of another person who compresses the spring by 0.34cm.
While John is travelling along an interstate highway, he notices a 139 mi marker as he passes through town. Later John passes a 116 mi marker. What is the distance between town and John's current location.
Compute the force of tension or compression
How close to the edge of the 28.0 kg table, that is 2.2m with legs 1.2m apart, can a 62.0 kg person sit without tipping it over.
Assume a neuron in the brain carries a current of. Treating the neuron as a straight wire, what is the magnetic field it produces at a distance of 7.50.
A car is moving at a constant velocity for 3s until it is 3.0 m from a yellow light. It slows to a stop in 2.0s. It remains stopped for 50s and then speeds up for 2s.
A cart loaded with bricks has a total mass of 21.2 kg and is pulled at constant speed by a rope. The rope is inclined at 27.2 ? above the horizontal and the cart moves 27.1 m on a horizontal floor. The coefficient of kinetic friction between groun..
Two objects with masses 5.60 kg and 1.40 kg hang 0.500 m above the floor from the ends of a cord 6.80m long passing over a frictionless pulley. Both objects start from rest. Find the maximum height reached by the 1.40kg object.
determine the value of IG. The support at B does not move while the measurement is taken. For the calculation, the horizontal location of G should be determined.
First work out the momentum before and after hitting the table. Don't forget the gravitational force.
A 27 pound meteorite struck a car, leaving a dent 26cm deep in the trunk. If the meteorite struck the car with a speed of 620m/s, what was the magnitude of its deceleration, assuming it to be constant.
