A spring with constant 185 N/m is compressed 1.38 m with a mass of 0.53 kg. How fast is it going 2.5 m above the ground?

Sagot :

The velocity 2.5 m above the ground will be 49.07 m/sec.

What is spring force?

The force required to extend or compress a spring by some distance scales linearly concerning that distance is known as the spring force. Its formula is;

F = kx

The formula for force is;

F=ma

Equating both the equation;

ma = kx

a=kx/m

a=( 185 N/m × 1.38 m) / 0.53

a  = 481.6 m/s²

The speed is found by Newton's third equation of motion;

v²=u²+2as

v²=0+2as

v²=2 × 481.6 m/s² × 2.5 m

v = 49.07 m/sec

Hence the velocity 2.5 m above the ground will be 49.07 m/sec.
