Q1. A 0.63 kg mass attached to a vertical spring of force constant 140 N/m oscillates with a maximum speed of 0.22 m/s. Find the following quantities related to the motion of the mass.
1. Find the Period.2. Find the Amplitude.3. Find the maximum magnitude of the acceleration.
Q2. A baseball pitcher can throw a ball with a speed of 70m/s. He is in the back of a pickup truck that is driving away from you. He throws the ball in the direction, and it floats toward you at a lazy 10 m/s.
Write down an expression for the efficiency of the air cart bumper in terms of the initial and final kinetic energy of the cart. What defines a collision as elastic or inelastic.
Long, long ago, on a planet far, far away, a physics experiment was carried out. First, a 0.250- ball with zero net charge was dropped from rest at a height of 1.70. The ball landed 0.400 later. Next, the ball was given a net charge of 7.85 and dropp..
What is the pressure inside the thermos
Find tension in the back muscle and the compressional force
A package is dropped from a passing plane (moving in the horizantal direction) and produces a projectile motion as it is falling to the ground. If it takes the package only 32.12 seconds until it hits the ground, how far above the ground was the plan..
The mass per unit length of the cord is 1.24 e-2 kg/m, so the mass of the cord is negligible compared to the mass of block. The cord is being vibrated at a frequency of 167 Hz (vibration source not shown in the drawing).
What is moment of inertia
Question: Field and force with three charges? What is the electric field at the location of Q1, due to Q 2 ?
Two identical spacecraft are to be accelerated by rockets. The first rocket fires with a force 4 times as large as that of the second rocket. The acceleration of the first rocket is how many times as vast as the acceleration of the second rocket.
You hang the rod vertically and attach a 74 kg mass to the bottom, and you observe that the bar becomes 1.74 cm longer. From these measurements, it is possible to conclude the stiffness of one interatomic bond in titanium.
In brief explain the changes that the Sun will go through after it exhausts its core hydrogen. Be sure to describe both the changes occurring in the Sun's core and the changes visible from outside the Sun. What do we mean by the stages we call hydrog..
