Q1. A hunter aims directly at a target (on the same level) 164 m away.
If the bullet leaves the gun at the speed of 300 m/s, by how much would it miss the target?
Q2. On another planet the simple pendulum consisting of a 0.154 kg mass suspended on a 1.20 m long string has a period of 3.860 seconds. What is acceleration on this planet?
What is an initial speed given to the rock
Coin is placed 14.0 from the axis of the rotating turntable of variable speed. When the speed of the turntable is slowly increased, the coin remains fixed on turntable until a rate of 40.0 (revolutions per minute) is reached, at that point the coin s..
A professor's office door is 0.80 wide, 3.0 high, and 5.0 thick; has the mass of 25; and pivots on frictionless hinges. A "door closer" is attached to the door and the top of door frame.
A hot wheels track has a spring loaded launcher. A 100g car is pushed into the launcher, which compresses the spring by 2cm. The cars initial velocity after launching is 3m/s.
What is an average speed
Determine the greatest vertical displacement of the pendulum (height). The mass lost by the rocket during these 30.0 is negligible. What impulse does an engine impart to the rocket?
A vessel whose walls are thermally insulated contains 2.00 of water and 0.550 of ice, all at a temperature of 0.0. The outlet of a tube leading from a boiler in which water is boiling at atmospheric pressure is inserted into the water.
A 430 microF capacitor is charged to 245 V. after that a wire is connected between the plates. How many joules of thermal energy are produced as capacitor discharges if all of the energy that was stored goes into heating the wire.
A 0.04 kg bullet collides in elastically with a 0.5 kg ballistic pendulum. Before the collision the pendulum was at rest but immediately after collision the pendulum is moving with speed of 13.6 m/s. How fast was the bullet travelling before the coll..
