devlian [24]
Force acting during collision is internal so momentum is conserve so (initial momentum = final momentum) in both directions Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1150 kg and was approaching at 5.00 m/s due south. The second car has a mass of 750 kg and was approaching at 25.0 m/s due west. Let Vx is and Vy are final velocities of car in +x and +y direction respectively. initial momentum in +ve x (east) direction = final momentum in +ve x direction (east)

- 750*25 + 1150*0 = (750+1150)
Vx initial momentum in +ve y (north) direction = final momentum in +ve y direction (north)

750*0 - 1150*5 = (750+1150)
Vy from here you can calculate Vx and Vy so final velocity V is


<span>V=<span>(√</span><span>V2x</span>+<span>V2y</span>) 
</span>
and angle make from +ve x axis is

<span>θ=<span>tan<span>−1</span></span>(<span><span>Vy</span><span>Vx</span></span>)

</span><span> kinetic energy loss in the collision = final KE - initial KE</span>

Ashley squirrel, named Jackie, rides on a bicycle with a constant kinetic energy of 3.6J. The mass of combination of Jackie and
yKpoI14uk [10]

The velocity of the combination of Jackie and the bicycle is 3.328 m/s.

Explanation:

From the given data the constant kinetic energy is 3.6 J. The mass of combination is 0.65 kg. To find the velocity of the combination of Jackie and the bicycle the formula  is

KE = 0.5 x mv2.

To find velocity,

V2=ke/(0.5×m)

V=\sqrt{(ke/(0.5*m)

v= 3.6/(0.5×0.65)

=\sqrt (11077/10)/10

v= 3.328 m/s

Hence, the velocity of the combination of Jackie and the bicycle is 3.328m/s.
