Answer :
The acceleration of an object is 10.3 m/s². The correct answer for acceleration is 10.3 m/s².
The initial velocity (u) is 10.5 km/h, the final velocity (v) is 99.8 km/h, and the time (t) is 2.41 seconds.
To calculate acceleration:
Acceleration (a) = Change in Velocity (Δv) / Time (t)
First, convert the velocities to meters per second:
1 km/h = 0.27778 m/s
So, the initial velocity (u) is 2.91 m/s, and the final velocity (v) is 27.71 m/s. Now, calculate acceleration (a):
a = (27.71 - 2.91 ) / 2.41
a = 24.80 / 2.41
a = 10.29 m/s²
Therefore, The acceleration is 10.3 m/s².
