Q. An 7.65g bullet is fired into a 260g block that is initially at rest at the edge of a frictionless table of height h = 1.11 m.
-The bullet remains in the block, and after the impact the block lands d = 1.90 m from the bottom of the table. How much time does it take the block to reach the ground once it flies off the edge of the table?
-What is the initial horizontal velocity of the block as it flies off the table? (assume this to be in the positive direction)?
-Determine the initial speed of the bullet
You can ignore friction between the sled and surface of the pond. Use the work-energy theorem to find the speed of the sled at 3.00 m.
A super tanker with the mass of 3.36 × 109 kg is moving with a constant velocity. Its engines generate a forward thrust of 4.11 × 105 N. Determine (a) magnitude of the resistive force exerted on the tanker by the water and (b) magnitude of the upward..
Three point charges are arranged at the corners of a square, with charge -Q on both the particle at the upper left corner and the particle at the lower right corner and with charge +2Q on the particle at the lower left corner.
If the LED emits light from a circle with diameter 10mm and is to couple to the fiber which has a50 micro meter diameter core .assume it radiates with afull cone angle 30 degree.
An airoplane takeoff speed is 320km/h. if its average acceleration is 2.9m/s^2, how long is it on runway after starting its takeoff roll.
A wire is stretched between two posts. Another wire is stretched between two posts that are four times as far apart. The tension in the wires is the equal, and they have the same mass.
The car's motion can be divided into three different stages: its motion before the driver realizes he's late, its motion after the driver hits the gas (but before he sees the police car), and its motion after the driver sees the police car. Which of ..
A spring with constant k=15 N/m hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. it is then pulled down 6 cm and free. if the ball makes 30 oscillations in 20 seconds, what are its maximum speed.
A 270 m wide river flows due east at a uniform speed of 2.30 m/s. A boat with the speed of 8.4 m/s relative to water leaves the south bank pointed in a direction 38o west of north. What is (a) magnitude and (b) direction of the boat's velocity rel..
A 67.3 kg sled starts at rest on a horizontal road. The coefficient of kinetic friction between the sled and the road is μk = 0.202. A man pulls the sled a distance 5.07 m along the ground by exerting a constant force of magnitude 532 N on a rope tha..
Janet jumps off a high diving platform with a horizontal velocity of 1.55 m/s and lands in the water 1s later. How high is the platform? The acceleration of gravity is 9.80 m/s2.
A crate of 31.9- tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it and observe that the crate just begins to move while your force exceeds 345. After that you must reduce your push to 247 to keep it moving at a..
