Answer:
Explanation:
Let hockey puck is moving at constant speed v
so here we have
so time taken by the puck to strike the wall is given as
now time taken by sound to come back at the position of shooter is given as
so we know that total time is 1.9 s
now we have
Answer:
k = 26.25 N/m
Explanation:
given,
mass of the block= 0.450
distance of the block = + 0.240
acceleration = a_x = -14.0 m/s²
velocity = v_x = + 4 m/s
spring force constant (k) = ?
we know,
x = A cos (ωt - ∅).....(1)
v = - ω A cos (ωt - ∅)....(2)
a = ω²A cos (ωt - ∅).........(3)
now from equation (3)
k = 26.25 N/m
hence, spring force constant is equal to k = 26.25 N/m
