Problem 7 4.A projectile of mass 9.6 kg is launched from the ground with an initial velocity of 12.4 m/s at an angle of 54° above the horizontal (see the figure). At some time after its launch, an explosion splits the projectile into two pieces. One piece, of mass 6.5 kg, is observed at 1.42 seconds after the launch to be at a height of 5.9 m and at a horizontal distance of 13.6 m from the launch point. Find...
Dr. C. #1: Exploding Projectile: A projectile of mass 9.6 kg is shot from the ground with an initial velocity of 12.4 m/s at an angle of 54° above the horizontal. A. Assuming the ground underneath the projectile's path is flat, what is the maximum height h the projectile reaches, its horizontal range R, and the time it spends in the air? Suppose that, at the peak of the projectile's motion, an explosion splits the projectile in half and one...
A projectile of mass M #13.4 kg is launched over level ground at a speed 28.6 and at an angle of 46.5 degrees above the horizontal. At the instant that the projectile is at what would be its highest point it explodes into two pieces; after the explosion there is a piece of mass ml = 5.2kg which has a vertical component of velocity of 9.7 , and a second piece of mass m2 which moves downwards. The explosion does...
A projectile is launched at an initial velocity of 150i+200j m/s (vector) over a horizontal surface. The object’s mass is 120kg. At t=5.0s, the projectile explodes to 3 pieces: a 35 kg piece with a velocity of -15i+25j m/s, a 60 kg piece with a velocity of 80i m/s and a 25 kg piece with velocity 549i+685j m/s. a) determine the impulse that acted on the 35 kg piece during the explosion B) assuming that the average force on the...
PLEASE ANSWER COMPLETELY A projectile of mass m launched vertically upward from the origin (0,0) with an initial velocity of vo explodes into three pieces when it reaches its maximum height of 490.0 m. Immediately after the explosion, one piece with mass m/4 is observed to have velocity v 3vot vo/2 y, and a second piece also of mass m/4 is observed to have velocity v Vox (a) What is the velocity v of the third piece immediately after the...
A 0.650 kg projectile is launched from the edge of a cliff with an initial kinetic energy of 1425 J and at its highest point is 177.6 m above the launch point. What is the horizontal component of its velocity? What was the vertical component of its velocity just after launch? At one instant during its flight the vertical component of its velocity is 35.40 m/s. At that time, how far is it above or below the launch point?
1. A firework (small rocket) whose shell has a mass of m 12kg was initially on the ground before being launched to a height of 100m above the ground at which point its horizontal displacement from its starting position is 17.6m. At this location its speed is 68m/s and it's at an angle relative to (and above) the horizontal of 80 as depicted in the diagram below. Once it reaches this height it goes off and its shell splits into...
At an Independence Day celebration show, a large firework is shot from the ground and, in the first stage of its bursting pattern, splits into two unequal parts. Assume that the firework has a mass of m_o = 0.30 kg and is launched from a cannon at an angle of theta_o= 48.8° with an initial velocity of v= 20 m/s. Just as the firework reaches its hight point in its trajectory, it explodes into two pieces. Immediately after the explosion,...
At time t = 0, a projectile is launched from ground level. At t = 2.00 s, it is displaced d = 51 m horizontally and h 76 m vertically above the launch point, what are the (a) horizontal and (b) vertical components of the initial velocity of the projectile? (c) At the instant it reaches its maximum height above ground level, what is its horizontal displacement D from the launch point?
You launch a projectile at an initial speed of 38.8 m/s from the ground. After 2.40 seconds of flight, the projectile lands on the ground. At what angle above the horizontal was the projectile launched? O 17.7 degrees 24.8 degrees 0 12.6 degrees O 12.4 degrees
