Answer: F = 1391 N
Explanation:
The information given to you are:
Mass M = 1300 kg
Acceleration a = 1.07 m/s^2
The magnitude of the force striking the building will be
F = ma
Where
F = force
Substitute mass M and acceleration a into the formula
F = 1300 × 1.07
F = 1391 N
Therefore, the wrecking ball strikes the building with a force of 1391 N

Answer:
Young modulus = 9.8 × 10⁹ N/m²
Explanation:
From the information given:
Stress = F/A
Stress = (10 × 9.8) / 0.001²
Stress = 9.8× 10⁷ N/m²
Strain = increase in length / initial length of wire
Strain = 0.02/ 2
Strain = 0.01
Now;
The Young modulus (Y)= stress/strain
Young modulus = (9.8 × 10⁷ N/m²) / 0.01
Young modulus = 9.8 × 10⁹ N/m²
