Acceleration of motorcycle= 1.23m/s^2
Step-by-step explanation:
We need to find the acceleration of motorcycle When its speed increases from 10km/hr to 50km/hr in 9 seconds
Given:
Initial speed= 10km/hr
Final speed= 50km/hr
Time = 9 seconds
Acceleration = ?
Formula:
Solution:
We will first convert the speed from km/hr to m/s
Converting Initial speed 10km/hr into m/s
1 km = 1000 m
10 km = 10,000 m
and 1 hr = 3600 s
So, Initial speed = 10,000/3600 = 2.77 m/s
Converting Final speed 50km/hr into m/s
1 km = 1000 m
50 km = 50,000 m
and 1 hr = 3600 s
So, Initial speed = 50,000/3600 = 13.88 m/s
Now Using formula of acceleration:
So, Acceleration of motorcycle = 1.23m/s^2
