- A 0.450 kg hammer is moving horizontally at 9.50 m/s when it strikes a nail and comes to rest after driving it 1.00 cm into a board. (a) Calculate the duration of the impact. s(b) What was the average force exerted on the nail? NBall 1 has a mass of 2.0 kg and is suspended with a 3.0 m rope from a post so that the ball is stationary. Ball 2 has a mass of 4.0 kg and is tied to another rope. The second rope also measures 3.0 m but is held at a 60.00 angle, as shown in Figure below. When ball 2 is released, it collides head-on, with ball 1 in an elastic collision. 3.0 m 60.0⁰ 3.0 m 2 4.0 kg 1 2.0 kg So far Ek = Eg 1/2 m2 V₁2² = m2gAy Vf₁ = (m₁-m₂/m₁ + m2)vi1 + (2m2/m1 + m2) V₁2 Vf2 = (m₂-mi/m₁ + m2)vi2 + (2m₁ /m₁ + m2) vil For the second part, you need to calculate the Eg₁ = Eki and Eg2 = Ek2, substitute the value of h and find the h maximum for 1 and 2 balls.A rifle with a weight of 25 N fires a 4.7-g bullet with a speed of 250 m/s.
