Question

Two masses m1 = 7 kg and m2 = 14 kg undergo an elastic collision as shown where θ = 30o. You know that m1 has
an initial speed v1i = 8.6 m/s and you know that m2 has an initial speed v2i = 2.6 m/s before the collision. Calculate
the final speed after the collision v1f for the first mass m1.

Two masses mı = 7 kg and m2 = 14 kg undergo an elastic collision as shown where 0 = 30°. You know that m1 has
an initial speed vii = 8.6 m/s and you know that m2 has an initial speed v2i = 2.6 m/s before the collision. Calculate
the final speed after the collision vif for the first mass m1.
