Q1. 0.40 kg projectile is projected at 20 m/s at 35 degrees. It lands at its initial level with a velocity of 16 m/s at an angle of 55 above the horizontal. What is the impulse?

Q2. A 350 kg mass is supported on the wire attached to a 15 m long steel bar that is pivoted at a vertical wall and supported by the cable. The mass of the bar is 77.0 kg. (Take right and up to be positive)

(a) i.) With the cable attached to the bar 5.0m from the lower end as shown, find tension in the cable.
ii.)Find the components of the force exerted by the wall on the steel bar.

(b) A somewhat longer cable replaces the old and is attached to the steel bar 5 m from its upper end, connecting to the same place on the wall as before and maintaining the same angle between the bar and the wall.

i) Find the tension in the cable

ii) find the components of the force exerted by t he wall on steel bar.
