Question

a body starting from the rest moves with a uniform acceleration of 0.02 m/s² for 5 minutes. calculate the speed acquired and the distance travelled in this time.​

Answer 1

Answer:

Speed acquired = 1800 m/s

Distance travelled = 900 m

Explanation:

Tip: In questions of Physics, always try to begin answering by mentioning the information you've

been given. This proves to be much helpful in problem solving.

Given information-

• Initial velocity, u = 0 m/s (rest)
• )Final velocity, v = ?
• Uniform acceleration, a = 0.02 m/s²
• Time, t = 5 minutes = 5 * 60 = 300 seconds

By Newton's laws of motion,

v = u + at

=> v = 0 + 0.02 * (300)²

=> v = 0.02 * 90000 = 2 * 900

=> v = 1800 m/s

Again by Newton's laws of motion,

S = ut + (1/2)at²

=> S = 0t + (1/2)(0.02)(90000)

=> S = 900 m
