Answer:
0.8 m/s
Explanation:
From Newton's third law of motion,
Impulse on a body = Change in momentum of the body
Ft = m(v-u) ......................... Equation 1
Where F = force on the body , t = time, m = mass of the body, v = final velocity, u = initial velocity,
Note: Taking the direction of the initial velocity as negative,
Given: F = 1.76×10⁴ N, t = 5.5×10⁻² s, m = 110 kg, u = -8.0 m/s
Substitute into equation 1
1.76×10⁴ ( 5.5×10⁻²) = 110[v-(-8.0)]
968 = 110v+880
110v = 968-880
110v = 88
v = 88/110
V = 0.8 m/s
Hence the final velocity = 0.8 m/s
