A22.5 kg chair attached to a spring takes 1.30 s to complete one cycle of oscillation. with an astronaut sitting in the oscillating chair with feet off the floor, a full oscillation cycle takes 2.54 s. what is the astronaut's mass?

85.689 kg is the astronaut's mass.

Explanation:

Given data: m = 22.5 kg   and T = 1.3 sec

So, using the below formula,

Now, after putting the values of m and T in the above equation, we will find out the value of k which is as,

To remove the square root, take square on both sides, we get,

Now, we have the same string but this time we have different mass and different time. So, let the mass of the astronaut is and = 2.54 sec, k= 525.7 kg. Apply these values in the equation, we get,

Taking squares on both sides, we get,

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
