Question

[(b) 0.011 m/s)
12. A body moving with an initial velocity of 36 km/h accelerates uniformly at the rate of 4 m/s2 for 15 seconds. Calculate
the total distance travelled in 20 s and the final velocity.
[s = 600 m; v = 70 ms-
APPLICATION BASED QUESTIONS​

Answer 1

Final Velocity (v) = u + at

v = 10 + 4(15) = 70 m/s

Total distance travelled

v² - u² = 2as

70² - 10² / 8 = s

s = 4800/8 = 600m
