Text Solution `t = vsqrt(a_(1)a_(2))``v = tsqrt(a_(1)a_(2))``a_(1) = a_(2) sqrt(vt)``(1)/(v) = t sqrt(a_(1)a_(2))` Answer : B Related Videos371082962 0 2.1 K একটি দৌড় প্রতিযোগিতায় প্রথম স্থানাধিকারী দ্বিতীয় স্থানাধিকারীর তুলনায় v বেগ বেশি নিয়ে এবং t সময় কম নিয়ে প্রতিযোগিতা শেষ করল। যদি প্রথম ও দ্বিতীয় স্থানাধিকারী প্রতিযোগীদের ত্বরণ যথাক্রমে `a_1` ও `a_2` হয় তবে কোন সম্পর্কটি সঠিক? 76133030 0 8.3 K 3:50 150 धावकों द्वारा 110 मीटर की बाधा दौड़ में लिए गये समय (सेकंड में ), नीचे सारणीबद्ध किए गए है : <br> <img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/X_HIN_MAT_C14_E06_007_Q01.png" width="80%"> <br> 14.6 सेकंड से कम दौड़ समाप्त करने वाले धावकों की संख्या है : 243137276 0 3.5 K 3:39 Eight runners in a race are equally likely to win the race. What is the probability that the race will be won by the runner in lane 1 OR the runner in lane 8? 643373384 0 3.3 K 3:23 Three runners A,B and C run a race, with runner A finishing 12 meters ahead of runner B and 18 meters ahead of runner C, while runner B finishes 8 meters ahead of runner C. Each runner travels the entire distance at a constant speed. The length of the race is: 647367104 0 8.2 K 2:17 In a 800 m race around a stadium having the circumference of 200 m, the top runner meets the last runner on the 5th minute of the race. If the top runner runs at twice the speed of the last runner, what is the time taken by the top runner to finish the race ? 306874671 0 6.7 K 2:01 दो धावक क्रमशः 7 मीटर/सेकंड तथा 5 मीटर/सेकंड की चाल से एक ही दिशा मे किसी रेस में दौड़ रहे हैं, दूसरे धावक के सापेक्ष पहले धावक का वेग होगा। Show More Comments Add a public comment...

(266 m) Here is what you start with: x = ? Dt = 14 s.
What is the final speed of the car in meters per second?This means that the initial velocity is zero and the final velocity is 60 miles per hour (26.82 meters per second). In other areas of the world, it's 0 to 100 km/h (27.78 meters per second).
What is the acceleration of a car whose speed increases?If the speed is increasing, the car has positive acceleration. When the car slows down, the speed decreases. The decreasing speed is called negative acceleration. In both cases, the car is accelerating, but one acceleration is positive and one is negative.
