Question

b) A hockey player applies an average force of 80N to a 0.25kg hockey puck for a time of 0.2s. Determine the impulse experienced by the hockey puck.

Answer 1

Answer:-

$\red{\bigstar}$ Impulse $\large\leadsto\boxed{\rm\purple{16 \: kgms^{-1}}}$

• Given:-

Force applied = 80 N

Mass of Hockey puck = 0.25 kg

Time = 0.2 sec.

• To Find:-

Impulse experienced by the hockey puck

• Solution:-

We know,

★ $\large\underline{\boxed{\pink{\bf I = F \triangle T}}}$

here,

I = Impulse

F = force applied

∆T = change in initial and final time

Hence,

➙ $\sf I = F \times (t_f - t_i)$

➙ $\sf I = 80 \times (0.2 - 0)$

➙ $\sf I = 80 \times 0.2$

★ $\bf I = 16 \: kgms^{-1}$
