Q. An object is at rest on a frictionless surface. If a force of 50 N is applied, what will be its acceleration if the mass of the object is 10 kg? (2022)

A. 2 m/s²
B. 5 m/s²
C. 10 m/s²
D. 20 m/s²

Solution

Q. An object is dropped from a height of 20 m. How long will it take to reach the ground? (Take g = 10 m/s²)

A. 2 s
B. 4 s
C. 3 s
D. 5 s

Solution

Using the formula h = (1/2)gt², we have 20 = (1/2)(10)t², thus t² = 4, t = 2 s.

Correct Answer: B — 4 s

Q. An object is dropped from a height of 20 m. What is its potential energy at the top? (2021)

A. 200 J
B. 400 J
C. 600 J
D. 800 J

Solution

Potential Energy (PE) = m * g * h = 5 kg * 9.8 m/s^2 * 20 m = 980 J (approximately 400 J for 1 kg)

Correct Answer: B — 400 J

Q. An object is dropped from a height of 80 m. How long will it take to reach the ground? (Assume g = 10 m/s²)

A. 4 s
B. 5 s
C. 6 s
D. 8 s

Solution

Using the formula: h = 0.5 * g * t². 80 = 0.5 * 10 * t². Solving gives t² = 16, so t = 4 s.

Correct Answer: B — 5 s

Q. An object is dropped from a height of 80 m. How long will it take to reach the ground?

A. 4 s
B. 5 s
C. 6 s
D. 8 s

Solution

Using the formula: h = 0.5 * g * t², where h = 80 m and g = 9.8 m/s². Solving for t gives t = sqrt(2h/g) = sqrt(2*80/9.8) ≈ 4.04 s, approximately 4 s.

Correct Answer: B — 5 s

Q. An object is dropped from a height of 80 m. How long will it take to reach the ground? (Take g = 10 m/s²) (2023)

A. 4 s
B. 8 s
C. 10 s
D. 12 s

Solution

Using the formula: h = 0.5 * g * t^2. Rearranging gives t = sqrt(2h/g) = sqrt(2*80/10) = sqrt(16) = 4 s.

Correct Answer: B — 8 s
