Answer:
I = 20 i ^ N s
Explanation:
For this problem let's use the Impulse equation
I = Δp = m
- v₀
The impulse and the velocity are vector quantities, let's calculate on each axis, let's decompose the velocity
cos 60 = vₓ / v
vₓ = v cos 60
sin60 =
/ v
= v sin60
vₓ = 10 cos 60
= 10 sin60
vₓ = 5.0 m / s
= 8.66 m / s
Let's calculate the impulse on each axis
X axis
Iₓ = m
- m vₓ₀
How the ball bounces
= - vₓ₀ = vₓ
Iₓ = 2 m vₓ
Iₓ = 2 2 5
Iₓ = 20 N s
Y axis
= m
- m vyo
On the axis and the ball does not change direction so
= vyo
= 0
The total momentum is
I = Iₓ i ^ +
j ^
I = 20 i ^ N s

Answer:
33627.4 N/m
Explanation:
By Hook's law F = k x
where F= force applied
K= Spring constant
x= distance it compresses.
Since the force applied in this case will be the weight of the object that causes it to compress, so, the weight will be (175 * 9.8) = 1715N force which causes a compression (x) of 0.0510m.
So,
F = K x
K = F / x
K = 1715 / 0.0510
K = 33627N/m
