Acceleration = (change in speed) / (time for the change)
Change in speed = (speed at the end) - (speed at the beginning).
Change in speed = (132 m/s) - (zero m/s) = 132 m/s
Acceleration = (132 m/s) / (3.94 s)
Acceleration = (132/3.94) m/s²
<em>Acceleration = 33.5 m/s² </em>(about 3.4 G's)
Answer:
Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
Inertia is the resistance of an object to moving or stopping
Answer:
41.74 m/s
Explanation:
The energy used to draw the bowstring = the kinetic energy of the arrow.
Fd = 1/2mv²................................ Equation 1
Where F = force, d = distance move string, m = mass of the arrow, v = speed of the arrow.
make v the subject of the equation
v = √(2Fd/m)...................... Equation 2
Given: F = 201 N, m = 0.3 kg, d = 1.3 m.
Substitute into equation 2
v = √(2×201×1.3/0.3)
v = √(1742)
v = 41.74 m/s.
Hence the arrow leave the bow with a speed of 41.74 m/s
