A sine wave is traveling along a string. The time for a particular point to move from maximum displacement to zero is 0.880 s. What is the period?
Find out the acceleration of the crate if the applied force is 380 , the mass of the crate is 32 and the coefficient of kinetic friction is 0.42.
The drawing shows one horizontal wire with the current going up and one vertical wire with the current going to the right. Point A is dH to the right and dV above the intersection. Point B is dH to the left and dV below the intersection.
A basketball player makes a jump shot. The 0.600 kg ball is released at a height of 2.00 m above the floor with a speed of 7.20 m/s. The ball goes through the net 3.10 m above the floor at a speed of 4.20 m/s Find the work done on the ball by air ..
Sketch a graph of maximum kinetic energy, KE max against visible light frequency, v for this experiment Label threshold frequency Vc.
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.
An Olympic basketball player shoots towards a basket that is 5.36m horizontally from her and 3.05m above the floor. The ball leaves her hand 1.83m above the floor at an angle of 45.0o above the horizontal. What initial speed must she give the ball so..
A block slides down an inclined plane, starting from rest and being pushed with a constant acceleration of 4.60 m/s2 over the distance of 20.80 cm. It then decelerates at the constant rate of 1.03m/s2 (because of friction), until it again comes to..
A cylinder of gas at room temperature (20°C) has a pressure p1. To what temperature in degrees Celsius would the temperature have to be increased for pressure to be 2.7p1.
A 62.00kg student is standing atop a spring in an elevator that is accelerating upward at 3.8 m/s2. The spring constant is 2600-N/m. By how much is the spring compressed.
A 340 kg piano slides 3.7 m down a 33° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction is 0.37.
A rocket ship at rest in space gives a short blast of its engine, firing 90 kg of exhaust gas out the back end with an average velocity of 700 m/s.
Find a relation between the variables that would guarantee that the block is initially slowing down.
