A missile is shot straight up into the air. At the peak of its trajectory, it breaks up into three pieces of equal mass, all of which move horizontally away from the point of the explosion. One piece travels in a horizontal direction of 35° east of north with a speed of 31 m/s. The second piece travels in a horizontal direction of 11° south of west with a speed of 7 m/s. What is the velocity of the remaining piece?
Homework Answers
hsing conservation of momentum
p1 + p2 + p3 = 0
m v1 + m v2 + m v3 = 0
31 ( sin 35 i + cos 35 j) + 7 ( - cos 11i - sin 11j) + v3 = 0
v3 = - 10.91 i - 24.06 j
net magnitude of velocity
v = 26.416 m/s

Several large firecrackers are inserted into the holes of a bowling ball, and the 6.1 kg ball is then launched into the air with a speed of 9.1 m/s at an angle of 42° from the horizontal. The firecrackers explode at the peak of the trajectory, breaking the ball into three pieces. A 2.0 kg piece travels straight back horizontally with a speed of 2.6 m/s. A 2.5 kg piece travels straight up with a speed of 1.7 m/s. What...

Explosion Problem: A three-piece explosion A 10.0 g projectile is traveling east at 2.0 m/s when it suddenly explodes into three pieces. A 3.0 g fragment is shot due west at 10 m/s while another 3.0 g fragment travels 40◦ north of east at 12 m/s. What are the speed and direction of the third fragment? Show and explain the steps for calculation.

Suppose a 11.0 kg fireworks shell is shot into the air with an initial velocity of 72.0 m/s at an angle of 80.0° above the horizontal. At the highest point of its trajectory, a small explosive charge separates it into two pieces, neither of which ignite (two duds). One 9.00 kg piece falls straight down, having zero velocity just after the explosion. Neglect air resistance (a poor approximation, but do it anyway). Calculate the velocity (in m/s) of the 2.00...

One billiard ball is shot east at 2.2 m/s. A second, identical billiard ball is shot west at 0.8 m/s. The balls have a glancing collision, not a head-on collision, deflecting the second ball by 90° and sending it north at 1.50 m/s. What are the speed and direction of the first ball after the collision? ___ m/s ____ degree south of east

A cannonball of mass 22.4 kg is shot into the air at an angle of 45 degrees with respect to horizontal. At the top of its ballistic trajectory, the cannonball suddenly explodes into two separate pieces, a smaller piece that is 1/3 the original mass, and a larger piece that is 2/3 the original mass. The two pieces fly apart horizontally, and the smaller piece ends up landing right back at the spot where the cannonball was originally launched, 11.2...

Kyle, a 100.0 kg football player, leaps straight up into the air (with no horizontal velocity) to catch a pass. He catches the 0.430 kg ball precisely at the peak of his jump, when he is 0.386 meters off the ground. He hits the ground 0.0295 meters away from where he leapt. If the ball was moving horizontally when it was caught, how fast was the ball traveling? ball's speed: m/s
