I think it’s 15cm
Might be 7cm
When looking for distance you multiply speed by time
So 15 x 2 = 30
30 is the distance between his house and school
The acceleration due to gravity on Earth is 9.8 m/s per second.
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
Answer:
Right now I have three.
Explanation: Thanks for the points luv ^-^.
