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
