A javelin thrower exerts an average force of 500 N on the javelin as it is displaced 1.5 m. The force is in-line and in the same direction of the javelin's displacement. Assume the javelin has a mass of 0.80 kg, had an initial velocity of 0 m/s, and had no change in its vertical position while work was performed on it. Calculate the final velocity of the javelin.
A. 21.65 m/s
B. 30.62 m/s
C. 43.30 m/s
D. 52.95 m/s

Answer #2
As given that there is no change in vertical position of
javeline during motion, so we can consider here straight line
motion. And we can find final velocity(v).

A spring of negligible mass stretches 3.00 cm from its relaxed
length when a force of 7.30 N is applied. A 0.520-kg particle rests
on a frictionless horizontal surface and is attached to the free
end of the spring. The particle is displaced from the origin to
x = 5.00 cm and released from rest at t = 0.
(Assume that the direction of the initial displacement is positive.
Use the exact values you enter to make later calculations.)

One end of a spring with a force constant of k = 10.0
N/m is attached to the end of a long horizontal frictionless track
and the other end is attached to a mass m = 2.20 kg which
glides along the track. After you establish the equilibrium
position of the mass-spring system, you move the mass in the
negative direction (to the left), compressing the spring 2.03 m.
You then release the mass from rest and start your stopwatch,...
