A block is attached to the end of a horizontal ideal spring and rests on a frictionless surface. The other end of the spring is attached to a wall. The block is pulled away from the spring's unstrained position by a distance x0 = 0.050 m and released from rest. The period of the subsequent periodic motion of the block is 0.64 s.
At what distance from the unstrained position is the speed of the block equal to 0.30 m/s?
Energy is transferred in solids by conduction, which means that. Heat travels in both directions. Heat travels from the cooler object to the hotter object. Heat does not travel between objects of different temperatures.
In an organ pipe open at one end and closed at the other, the fundamental frequency emitted is 240 Hz. find the next overtone frequency
it is important for the body to have mechanisms to effectively cool itself if not moderate exercise could easily
A 260-kg piano slides 4.2m down a 30° 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 0.40.
A coin rests 13.3 cm from the center of a turntable. The coefficient of static friction among the coin and turntable surface is 0.350. The turntable starts from rest at t = 0 and rotates with a constant angular acceleration of 0.628rad/s2.
A spacecraft is traveling with a velocity of v0x = 4330 m/s along the +x direction. Two engines are turned on for a time of 728 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 1.74 m/s2.
