Question

Object a travels in the +x-direction before hitting a stationary object

Answer 1

The object’s resultant angle of motion with the +x-axis after the collision is 47°

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, tanФ = $\frac{y}{x}$

⇒tanФ = $\frac{6.2 × 10^4 }{5.7 × 10^4}$

⇒tanФ = 1.088

⇒ Ф = $tan^{-1}$ 1.088 
         =  47.4 ≈ 47
