I have honestly never read anything about a car being disseminated,
or any instructions on how to do it, or any of the theory behind it.

<span>The solution is: Earth circumference is 2*pi*r=25,130 miles 25,130 miles corresponds to 360Âş, so 5,000 miles corresponds to 360*5000/25130 = 71,6Âş 71,6Âş is equivalent to 71,6*2pi/360=1,25 radians Angular velocity is 1,25/9=0,139 rad/h</span>

Dan is gliding on his skateboard at 2.00 m/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at

miss Akunina [59]

Answer:

The velocity of Dan is 1.13 m/s.

Explanation:

Given that,

Initial velocity of skateboard and Dan = 2.00 m/s

Velocity of skateboard = 7.00 m/s

Mass of Dan m= 40.0 kg

Mass of skateboard M= 7.00 Kg

Suppose How fast is Dan going as his feet hit the ground?

We need to calculate the initial velocity of Dan

Using conservation of momentum

$(m+M)v_{i}=mv_{f}+Mv_{f}$

Put the value into the formula

$(40.0+7.00)\times2.00=40.0\times v_{i}+7.00\times7.00$

$v_{i}=\dfrac{(40.0+7.00)\times2.00-7.00\times7.00}{40.0}$

$v_{i}=1.13\ m/s$

Hence, The velocity of Dan is 1.13 m/s.
