Q. A hunting how imparts an acceleration of 5300.m/s^2 to a 29.3 g arrow at an angle of 15.0 degrees to the horizontal. What is the horizontal component of the force exerted by the bow on the arrow?
Q. A 700-N car traveling at 25 m/s.The breaks are applied suddenly and the car slides to a stop. The average breaking force between the tires and the road is 7100N.How far will the car slide once the breaks are applied?
Please helps me out for determining the following if the capacitor in the circuit below is initially uncharged.
A 9 turn coil 1.80 in diameter is rotated at 11 about an axis perpendicular to a uniform magnetic field. A voltmeter connected to the coil through rotating contacts reads a peak value of 340.
An 8g bullet is fired at a speed of 216 m/s into a 190 g block that is initially at rest at the edge of a table of 1m height. The bullet fully embeds itself in the block before the bullet-block system launches off the table. How far in the x-direc..
General relativity says that the total orbital energy of the binary system consisting of two neutron stars will decrease over time through the emission of gravitational waves. If this happens slowly sufficient that the orbit stays circular, response ..
The bullet passes right through and emerges on the other side with a speed of 100 m/s, and the saxophone is given a speed of 4.8 m/s.
a) Determine the magnitude and direction of the electrostatic force acting on particle A in the figure given below due to particles B and C . The values of the charge on these particles are indicated in the figure.
A bullet of mass 0.0022 kg initially moving at 496 m/s embeds itself in a large fixed piece of wood and travels 0.64 m before coming to rest. Imagine that an acceleration of the bullet is constant.
The heating coil of a hot-water heater has a resistance of 20.0 and operates at 210 V. If electrical energy costs $0.080/kWh, what does it cost to raise 290 kg of water in the tank from 15 °C to 74° C.
Find the mass flow rate in through the vent in question #1 using the following well-known relationship for the mass flow into an opening:
A Ferris wheel is a vertical, circular amusement ride with radius 6 m. Riders sit on seats that swivel to remain horizontal. The Ferris wheel rotates at the constant rate, going around once in 6.4 s. Consider a rider whose mass is 70 kg.
A luge and its rider, with a total mass of 104 kg, emerges from a downhill track onto a horizontal straight track with the initial speed of 53 m/s. suppose they stop with the constant deceleration of 2.30 m/s2.
How many 104W lightbulbs can you use in a 113 V circuit without tripping a 17 A circuit breaker? (The bulbs are connected in parallel that means that the potential difference across each lightbulb is 113V.)
