Answer:
Acceleration a =-1.75 m/s²
Explanation:
Given:
Initial speed u = 24 m/s
Final speed v = 10 m/s
Time taken t = 8 sec
Find:
Acceleration a
Computation:
a = (v-u)/t
a = (10-24)/8
a = -14 / 8
Acceleration a =-1.75 m/s²
Answer:
Accelaration =(v-u)/t
40-10/20m/s^2
30/20m/s^2
1.5m/s^2=accelaeration
