Croquet balls must have a mass of 0.50 kg. A red croquet ball, moving at 10

julsineya [31]

The final speed of the green ball : 8.5 m/s

<h3>Further explanation</h3>

Given

mass of Croquet ball = 0.5 kg

v₁= 10 m/s

v₁'= 1.5 m/s

Required

the final speed

Solution

The law of conservation of momentum

m₁v₁ + m₂v₂ = m₁v₁ '+ m₂v₂' (1=red croquet ball, 2=green croquet ball)

v₂=0 (at rest)

Input the value :

$\tt 0.5\times 10+0.5\times 0=0.5\times 1.5+0.5\times v_2'\\\\5=0.75+0.5v_2\\\\4.25=0.5v_2\rightarrow v_2=8.5~m/s$

1.Calculate the end velocity of a rocket that traveled 16km in 2 seconds.

fomenos

Answer:

1}800m/s

2}80m/s²

Explanation:

1]first convert the kilometers to meters so as to obtain similar units;

16×1000=16000m (1Km=1000m)

then divide the ditance by time:

speed=distance/time

=16000m/2s

=800m/s

2]acceleration=(initial velocity -final velocity)/time taken

=(800m/s-0m/s)/10s

=800m/s/10s

=80m/s²
