Since the average speed of the two parts is different therefore
it can not fall at a constant speed.
Therefore we can say that the speed in the two parts must be
different.
Now in the first part the average speed was 0.78 while in the
second part it became 0.96 m/s
so we can conclude that the speed must be increase that's why
average speed has increased.

In the first part of the experiment, one group of students recorded 1.349 m and 0.809 m as their Range and Height measurements, respectively. What is the marble's initial muzzle speed in m/s unit? Enter your number with correct amount of significant figures, assuming g=9.80 m/s2.
a. An attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s from a height of 1.55 m above the ground. Will the rock reach the top of the wall? If so, how fast is it moving when it reaches the top. If not, what initial speed must it have to reach the top? b. To defend the castle, a rock is thrown downwards from the top of the wall with...

Can you please solve and explain your work? The correct answer is 7.35 m/s. A block with mass 0.500 kg is attached to a horizontal spring and moves in simple harmonic motion on a horizontal frictionless surface. The spring has a force constant 400N/m. The amplitude of the motion is 0.300 m. What is the speed of the block during its oscillations when it is displaced 0.150 m from its equilibrium position? (this was part 2 of a question, in...
I keep getting Part C wrong! Please HELP!

Problem 9.41 Part A A 3.0-kg block slides along a frictionless tabletop at 8.0 m/s toward a second block (at rest) of mass 4.5 kg. A coil spring, which obeys Hooke's law and has spring constant k = 720 N/m , is attached to the second block in such a way that it will be compressed when struck by the moving block. (Figure 1) What will be the maximum compression of the spring? Express your answer using two significant figures...
