A spring is used to launch a coffee mug. The 20cm long spring can be compressed by a maximum of 8cm. The mug has a mass of 350 g
Zepler [3.9K]

Answer:

7503.13 N/m

Explanation:

Use principle of conservation of energy.

Here, energy stored in the spring due to compression shall be utilized in attaining the potential energy of the mug.

Given that,

Length of the spring = 20 cm = 0.20 m

Compression, x = 8 cm = 0.08 m

mass of the mug, m = 350 g = 0.35 kg

h = 7 m

use the expression for energy balance -

(1/2)*k*x^2 = m*g*h

=> k = (2*m*g*h) / x^2

input the values

k = (2*0.35*9.8*7) / 0.08^2

= 7503.13 N/m

A cyclist rides in a circle with speed 5 m/s. What is his centripetal
Reptile [31]

Answer: 1.32 m/s^2

Explanation:

Centripetal acceleration is given by the formula

a = ( v^2 ) / r

where a is centripetal acceleration, v is velocity and r is radius.

We know that,

v = 5 m/s

r = 19m

Now,

a = ( v^2 ) / r

a = ( 5^2 ) / 19

a = 25 / 19

a = 1.32 m/s^2
