A student uses a spring loaded launcher to launch a marble vertically in the air. The mass of the marble is

GarryVolchara [31]

Answer:

Part a)

When spring compressed by 2 cm

H = 1.47 m

Part b)

When spring is compressed by 4 cm

H = 5.94 m

Explanation:

Part a)

As we know that the spring is compressed and released

so here spring potential energy is converted into gravitational potential energy at its maximum height

So we will have

$\frac{1}{2}kx^2 = mg(H + x)$

$0.5(220)(0.02)^2 = 0.003(9.81)(H + 0.02)$

so we have

$H = 1.47 m$

Part b)

Similarly when spring is compressed by 4 cm

then we have

$\frac{1}{2}kx^2 = mg(H + x)$

$0.5(220)(0.04)^2 = 0.003(9.81)(H + 0.04)$

so we have

$H = 5.94 m$

A supersonic airplane is flying horizontally at a speed of 2650 km/h. What is the centripetal acceleration of the airplane, if i

Andrew [12]

Answer:

$a_{c}=82617.65km/h^{2}\\ or\\a_{c}=6.37m/s^{2}$

Explanation:

Given data

Speed v=2650 km/h

Radius r=85.0 km

To find

Centripetal Acceleration

Solution

As centripetal acceleration is given as

$a_{c}=\frac{v^{2} }{r}................eq(i)$

where

v is velocity

r is the radius

Substitute the given values in eq(i)

$a_{c}=\frac{(2650km/h)^{2} }{85km} \\a_{c}=82617.65km/h^{2}\\ or\\a_{c}=6.37m/s^{2}$
