The velocity of a particle which moves along the s-axis
is given by s=40-3t^2 where t is in seconds.
Calculate the displacement delta s of the particle during
the interval from t=2 to t=4

24 units

Explanation:

Δs = ∫ v(t) dt

Δs = ∫₂⁴ (40 − 3t²) dt

Δs = (40t − t³) |₂⁴

Δs = (40(4) − (4)³) − (40(2) − (2)³)

Δs = (160 − 64) − (80 − 8)

Δs = 96 − 72

Δs = 24

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
