Question: 1 forces of 50 n easterly and 30 n northerly...

Question details

1. Forces of 5.0 N easterly and 3.0 N northerly are acting on a tree. Determine the resultant force acting on the tree. Include your vector diagram.

 

2.  (a) A 1600 kg van travelling west at 4 ms–1 collides with a 1200 kg car travelling east at 9 ms–1 . The vehicles lock together. a) Find the speed and direction of the tangled wreck immediately after the collision?

 

(b) The collision occurs in 0.5 s. Determine the average force of the 1600 kg van on the 1200 kg vehicle.

 

(c) What is the impulse on the 1200 kg vehicle due to the collision?
