Since we know that..
I = F . ∆t
= m . a . ∆t ( the puck accelerating after the collision with the hockey sticks)
= m . ∆v/∆t . ∆t
= m . ∆v
Solve for m, we get..
m = I / ∆v
= 4 / 12
= 1 / 3 kg or 0.33 kg
C. explicit and implicit :)
Explanation:
There are 3.28 feet in a meter.
1100 ft/s × (1 m / 3.28 ft) ≈ 335 m/s
Round as needed.

Complete Question
The complete question is shown on the first uploaded image
Answer:
a
b
Explanation:
From the question we are told that
The maximum height is H = 2.70
The Range is R = 12.9 m
Generally from projectile motion we have that
Generally from trigonometric identity
So
=>
Also the maximum height is
=>
=>
=>
=>
Dividing equation 2 by (1)
=>
=>
=>
So
From equation 1
=>
Generally the vertical component of the initial velocity is mathematically evaluated as
=>
=>
Generally the time taken is mathematically represented as
=>
=>
