You are the lead scientist for a criminal investigation unit. Your team has found what might be the gun that caused the murder.Unfortunately the bullet that identifies the gun can not be found,but there is enough evidence that if you can figure out the speed of the bullet at a distance of 100 meters from where the gun was fired,you will solve the case.

If you could figure out the exact point the gun was aimed, then you could measure the drop in 100yards.

A block weighing 130 Newtons on an incline is held back by a weight of 45 newton hanging from a cord tha passes over a frctionless pulley nd is attached to the blcok. Find the angle at which the block will slide down the plane at constant speed. the answer is 49 degrees, but I don't know how the textbook got there.
