A body starting from rest travels with uniform acceleration. if it travels 100 meters in 5 seconds then what is the value of acceleration |
|
Answer» Answer: 8 m/s square Explanation: Given, Initial velocity (u) = 0 Distance TRAVELLED (s) = 100 m Time taken (t) = 5 seconds Find, What is the VALUE of acceleration. Solution, USING the equation of motion, s = ut + 1/2at², it can be SUBSTITUTED by- 100 = 0 + 1/2a × 5× 5 100= 1/2a × 25 1/2a = 100/25 1/2a = 4 Therefore a (acceleration) = 4 × 2 = 8m/s square. |
