All plumps have the same speed
Because all have same initial velocity.
So by work energy theorem- work done by all forces equal to change in kinetic energy .
So here only force acting is gravity and work done by gravity is same for all cases .so their final velocities is also same as their final kinetic energy is also same.

1. (6 points) The figure shows three situations in which identical projectiles are launched (at the same level) at identical initial speeds and angles. The projectiles do not land on the same terrain, however (a) Rank the situations according to the final speeds of the projectiles just before they land, greatest first. (b) Rank the situations according to the final horizontal speeds of the projectiles just before they land, greatest first.

In the figure, two particles are launched from the origin of the
coordinate system at time t = 0. Particle 1 of mass
m1 = 5.80 g is shot directly along the
x axis (on a frictionless floor), where it moves with a
constant speed of 10.7 m/s. Particle 2 of mass
m2 = 1.80 g is shot with a velocity of
magnitude 25.0 m/s, at an upward angle such that it always stays
directly above particle 1 during its...

In the figure, two particles are launched from the origin of the coordinate system at time t = 0. Particle 1 of mass m1 = 3.20 g is shot directly along the x axis (on a frictionless floor), where it moves with a constant speed of 10.3 m/s. Particle 2 of mass m2 = 3.00 g is shot with a velocity of magnitude 19.2 m/s, at an upward angle such that it always stays directly above particle 1 during its...

A small, spring-loaded cannon launches a golf ball from level ground with an initial speed vi at an angle θi with the horizontal. The golf ball lands a horizontal distance R from its launch point. The highest point the golf ball reaches during its flight is a distance R/12 above the ground. In terms of R and g, find the following. (You may ignore air resistance.) (a) the time interval during which the golf ball is in motion t =...

Question 1 In the figure, two particles are launched from the origin of the coordinate system at time t = 0. Particle 1 of mass my - 5.20 g is shot directly along the x axis (on a frictionless floor), where it moves with a constant speed of 10.4 m/s. Particle 2 of mass m2 - 3.80 g is shot with a velocity of magnitude 17.0 m/s, at an upward angle such that it always stays directly above particle 1...

The
figure below shows three sets of cross sections of equipotential
surfaces; all three cover the same size region of space.
(a) Rank the arrangements according to the magnitude of the
electric field present in the region, greatest first (use only the
symbols > or =,for example1=2>3).
(b) In which is the electric field directed down the

The drawing shows two frictionless inclines that begin at ground level (h = 0 m) and slope upward at the same angle θ. One track is longer than the other, however. Identical blocks are projected up each track with the same initial speed v0. On the longer track the block slides upward until it reaches a maximum height H above the ground. On the shorter track the block slides upward, flies off the end of the track at a height...
