Acceleration= velocity/time
1.1/2.7=0.41
The acceleration is .41 m/s^2
Answer:
1.44%
Explanation:
The potential energy of a spring is given by
The kinetic energy is
Now x = 12 A
Applying in the first equation
The percentage would be 14400%
at (makes more sense)
The percentage is 25 % of the kinetic energy
Answer:
x=7227
y=1678
(7227,1678)
Explanation:
Ok, check the picture I attached you, because of the problem don't give us aditional information, let's asume that the projectile is fired from an initial position x=0 and y=0. Now let's use projectile motion equations, but firs let's find the initial velocity components in x-axis and y-axis:
Now, let's find the x coordinate with this equation:
Finally asumming a gravity constant g=9.8, let's find the y coordinate with the next equation:
