Answer:

The value of acceleration due to gravity on all objects near the surface of earth will be 9.8 m/s/s or 10 m/s/s(approx)

Explanation:

here we know that all objects near the surface of earth will experience the force of gravity towards the center of earth.

this force of gravity is given as

F = mg

now to find the acceleration due to this force we can say

a = \frac{F}{m}

here we will have

a = \frac{mg}{m}

a = g = 9.8 m/s^2 or 10 m/s^2

so acceleration due to gravity for all objects near the earth surface is nearly same or constant

A spring with spring constant 15 N/m hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is
olga nikolaevna [1]

Explanation:

It is given that,

Spring constant of the spring, k = 15 N/m

Amplitude of the oscillation, A = 7.5 cm = 0.075 m

Number of oscillations, N = 31

Time, t = 15 s

(a) Let m is the mass of the ball. The frequency of oscillation of the spring is given by :

f=\dfrac{1}{2\pi}\sqrt{\dfrac{k}{m}}

Total number of oscillation per unit time is called frequency of oscillation. Here, f=\dfrac{31}{15}=2.06\ Hz

m=\dfrac{k}{4\pi^2f^2}

m=\dfrac{15}{4\pi^2\times 2.06^2}

m = 0.0895 kg

or

m = 89 g

(b) The maximum speed of the ball that is given by :

v_{max}=A\times \omega

v_{max}=A\times 2\pi f

v_{max}=0.075\times 2\pi \times 2.06

v_{max}=0.970\ m/s

v_{max}=97\ cm/s

Hence, this is the required solution.
