Answer:
How does newtons first two laws of motion apply to the toy car?
Explanation:
The object’s resultant angle of motion with the +x-axis after the collision is 47°
<span>From object A:
1) x-momentum is 5.7 × 10^4 kilogram meters/second,
2) y-momentum is 6.2 × 10^4 kilogram meters/second.
Now, we know, tan</span>Ф =

⇒tanФ =

⇒tanФ = 1.088
⇒ Ф =

1.088
= 47.4 ≈ 47
