A Gas powered cannon shoots a projectile by introducing nitrogen gas at 20.5MPa into a cylinder have a inside diameter od 50mm ..compute the force exerted on the projectile

40251.7 N

Explanation:

Stress is given as Force per unit Area and expressed as where F is the force exerted and A is the area on which the force acts. Making F the subject of the formula then

Area, where r is radius which is equivalent to half the diameter. In this case, the diameter is given as 50 mm hence radius will be 25 mm and converted to meters it is 0.025 m

Substituting 20.5 MPa which is for then the force will be

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
