Easy

A car travels 120 meters in 4 seconds. What is its average speed during this time?

A. 35 m/s

B. 30 m/s

C. 25 m/s

D. 20 m/s

Show Answer & Explanation

Correct Answer: B

Average speed = total distance / total time = 120 m / 4 s = 30 m/s.

Easy

If a vehicle moves at a speed of 60 km/h, what is its speed in m/s?

A. 16.67 m/s

B. 18 m/s

C. 15 m/s

D. 14 m/s

Show Answer & Explanation

Correct Answer: A

To convert km/h to m/s, divide by 3.6. So, 60 km/h = 60 / 3.6 = 16.67 m/s.

Easy

A person walks 100 meters in 20 seconds. What is her average speed?

A. 4 m/s

B. 5 m/s

C. 6 m/s

D. 3 m/s

Show Answer & Explanation

Correct Answer: B

Average speed = total distance / total time = 100 m / 20 s = 5 m/s.

Medium

A car accelerates uniformly from rest to a speed of 30 m/s over a distance of 450 m. What is the magnitude of the car's acceleration?

A. 3 m/s²

B. 2 m/s²

C. 4 m/s²

D. 5 m/s²

Show Answer & Explanation

Correct Answer: A

Using the formula v² = u² + 2as, we can find acceleration. Here, u = 0, v = 30 m/s, and s = 450 m. Rearranging gives a = (v² - u²) / (2s). Plugging in values results in an acceleration of 3 m/s².

Medium

A particle moves along a straight line with its velocity given by v = 6t - 2, where v is in m/s and t is in seconds. Find the time when the particle comes to rest.

A. 2 seconds

B. 3 seconds

C. 4 seconds

D. 1 second

Show Answer & Explanation

Correct Answer: A

Setting v = 0 gives 6t - 2 = 0, solving gives t = 2 seconds.

Medium

A ball is dropped from a height of 45 m. How long does it take to reach the ground? (Take g = 9.8 m/s²)

A. 3 seconds

B. 2 seconds

C. 4 seconds

D. 5 seconds

Show Answer & Explanation

Correct Answer: A

Using the formula h = 0.5gt², solving for t gives t = √(2h/g) = √(2*45/9.8) ≈ 3 seconds.

Medium

A cyclist travels a distance of 500 m at a speed of 10 m/s. How long does the journey take?

A. 50 seconds

B. 40 seconds

C. 60 seconds

D. 30 seconds

Show Answer & Explanation

Correct Answer: A

Time = distance/speed = 500 m / 10 m/s = 50 seconds.

Hard

A particle moves in a straight line with an acceleration given by the equation a(t) = 6t - 4, where 't' is time in seconds. What is the velocity of the particle at t = 3 seconds if it starts from rest?

A. 26 m/s

B. 22 m/s

C. 20 m/s

D. 18 m/s

Show Answer & Explanation

Correct Answer: A

To find the velocity, integrate the acceleration function. Starting from rest means initial velocity is zero.

Hard

A car travels 100 m in the first 5 seconds and then accelerates to cover another 200 m in the next 10 seconds. What is the average velocity of the car during the entire motion?

A. 20 m/s

B. 18.75 m/s

C. 15 m/s

D. 25 m/s

Show Answer & Explanation

Correct Answer: B

Average velocity is total distance divided by total time. Here, total distance is 300 m and total time is 15 s.

Q10

Hard

A particle moves along a straight line such that its position as a function of time is given by s(t) = 5t^3 - 6t^2 + 7t. What is the acceleration of the particle at t = 2 seconds?

A. 36 m/s²

B. 30 m/s²

C. 24 m/s²

D. 16 m/s²

Show Answer & Explanation

Correct Answer: A

Acceleration is the second derivative of position with respect to time. Calculate s''(t) to find the acceleration.
