The acceleration of the puck is 43.75 m/s².
The velocity of an object or particle in uniform motion is defined as the rate at which its direction is changing as seen from a particular angle and as measured by a particular unit of time.
The player's puck accelerates from a velocity of 5 m/s to 30 m/s in the same direction.
The player's puck covers a distance of 10 m during that process.
Therefore,
The initial velocity of the puck is u = 5 m/s
The final velocity of the puck is v = 30 m/s
The distance covered during the period is s = 10 m
Using the equation of motion,
v² - u² = 2as
(30)² - (5)² = 2 × a × 10
900 - 25 = 20 × a
875 = 20 × a
a = 875/20
a = 43.75 m/s²
