A(n) 6 kg object moving with a speed of 8.6 m/s collides with a(n) 17 kg object moving with a velocity of 11 m/s in a direction 20◦ from the initial direction of motion of the 6 kg object. 8.6 m/s 11 m/s 17 kg 6 kg 20◦ What is the speed of the two objects after the collision if they remain stuck together? Answer in units of m/s.

The speed of the two objects after the collision if they remain stuck together is 10.26 m/s.

Explanation:

Given that,

Mass of object = 6 kg

Speed of object = 8.6 m/s

Other object = 17 kg

Velocity = 11 m/s

Angle = 20°

We need to calculate the speed of the two objects after the collision if they remain stuck together

Using conservation of momentum

Put the value into the formula

On x axis,

...(I)

On y axis,

....(II)

Squaring and addin equation (I) and (II)

Hence, The speed of the two objects after the collision if they remain stuck together is 10.26 m/s.
