a simple pendulum, 3 m in length, is released with a push when the support string is at an angle of 30 degrees force vertical. If the initial speed of the suspended mass is 1.2 m/s when at the release point, what is its speed at the swing.
A parachutist of mass 50kg jumps out of an airplane at a hight of 1000m. The parachute deploys, and he hits the ground with a velocity of 5m/s. Find the average resistance on the parachutist.
What current is in the primary circuit. A proton moves at a speed of 8.0 103 m/s as it passes through a magnetic field of 0.55 T. Find the radius of the circular path. Note down that the charge carried by the proton is equal to that of the electron..
A device known as Atwood\'s machine consists of two masses hanging from the ends of a vertical rope that passes over a pulley. Assume the rope and pulley are massless and there is no friction in the pulley.
Imagine that we drop a block of mass m from a height h above the comparatively lightweight plate supported by a vertical spring with relaxed length L and spring constant k. From what value of h would we have to drop the block to compress spring to..
A 2.65 kg object is moving in a plane, with its x and y coordinates given by x = 2t2 - 3 and y = 2t3 + 6, where x and y are in meters and t is in seconds. Find out the magnitude of the net force acting on this object at t = 2.00 s.
The collision between a hammer and a nail can be considered to be approximately elastic. Estimate the kinetic energy acquired by a 12-g nail
A car of mass 1110 kg travels at a speed of 20 ms-1 along a straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.83. Take the acceleration due to gravity to ..
Starting from rest, you pull the string with a constant force F = 8 N along a nearly frictionless surface. At the instant while the center of the disk has moved a distance x = 0.12 m, a length d = 0.27 m of string has unwound off the disk.
You are designing a process to store pressurized argon gas (a monatomic gas). If you pressurize the gas at a constant temperature, how much work must be done on the gas
A sample of a material has 40000 radioactive particles in it today. Your grandfather measured 80000 radioactive particles in it 60 years ago. how many radioactive particles will the sample have
A 0.5970-kg ice cube at -12.40°C is placed inside a chamber of steam at 365.0°C. Later, you notice that the ice cube has completely melted into a puddle of water, calculate the final temperature of the puddle once it settled to equilibrium
And if the plane could fly without this pilot, how much force would the plane require to maintain the equal acceleration?
In a European country a bathroom scale displays its reading in kilograms. When a man stands on this scale, it reads 86.1 kg. find the magnitude of the force he exerts on the chin-up bar
