Q. The minimum distance required to stop a car moving at 38.0 mi/h is 41.0 ft. What is the minimum stopping distance for the same car moving at 68.0 mi/h, assuming the same rate of acceleration?
Q. A 30.0 kg gun is resting on a frictionless surface. The gun fores a 50.0 g bullet with a muzzle velocity of 310.0 m/s.
a) Calculate the momenta of the bullet and the gun after the gun is fired.
b) Calculate the kinetic energy of both the bullet and the gun just after firing.
A 240 , 50.0-cm-diameter turntable rotates on frictionless bearings at 57 . A 22 block sits at the center of the turntable. A compressed spring shoots the block radically outward along a frictionless groove in surface of the turntable. What is turn..
The resistor is connected in series with total set of lightbulbs. What is the value of the resistance? What is the power loss in the resistor.
A bumper car with mass m1 = 115kg is moving to the right with a velocity of v1 = 4 m/s. A second bumper car with mass m2 = 95 kg is moving to the left with a velocity of v2 = -3.7 m/s. The two cars have an elastic collision. Suppose the surface is fr..
An astronaut on the Mars attaches a small brass ball to a 1.00- length of string and makes a simple pendulum. She times 13 complete swings in a time of 35.4 seconds. From this measurement she calculates the acceleration due to gravity on the Mars.
Will the car hit the barricade
An observer inside the building notices that it takes 0.15s for the tile to pass her window, whose height is 2.20m. How far above the top of this window is the roof.
A ball is thrown vertically upward with a speed of 1.63m/s from a point 4.21m above the ground. What is the time at which it will reach the ground.
A 21 g bullet travelling at 255 m/s is fired into a 0.452 kg wooden block anchored to a 100 N/m spring. How far is spring compressed to the nearest thousandth of a meter.
A cosmic-ray proton in interstellar space has an energy of 17.0 MeV and executes a circular orbit having a radius equal to that of Jupiter's orbit around the Sun (7.78 x 10^11 m). What is the magnetic field in that region of space.
The temperature of the glass surface of a 30 W light bulb is 75°C when the room temperature is 10°C. Estimate the temperature of a 150 W light bulb with a glass bulb the same size. Consider only radiation, and assume that 90% of energy is emitted as ..
A 7.5 nC charge is located 1.8m from a 4.2 nC charge. Find out the magnitude of the electrostatic force that one charge exerts on the other. Is the force attractive or repulsive.
