Q1. A crane on a wharf hoists A bag of cement whose mass is 3 kg; with g = 10 m/s^2, how heavy is the load it lifts?
- A.0.3 N
- B.30 N
- C.13 N
- D.3 N
Answer: B. 30 N
Weight W = m*g = 3 kg * 10 m/s^2 = 30 N (g = 10 m/s^2).
Q2. Inside a warehouse A water drum of mass 5 kg rests on a pallet; taking g taken as 10 m/s^2, what is its weight?
- A.15 N
- B.50 N
- C.5 N
- D.0.5 N
Answer: B. 50 N
Weight W = m*g = 5 kg * 10 m/s^2 = 50 N (g = 10 m/s^2).
Q3. A porter shoulders A steel girder having a mass of 8 kg; if g equals 10 m/s^2, what downward pull does he bear?
- A.18 N
- B.0.8 N
- C.80 N
- D.8 N
Answer: C. 80 N
Weight W = m*g = 8 kg * 10 m/s^2 = 80 N (g = 10 m/s^2).
