5 sec and with speed of T2 kmth for rent
15 sec. then find its anciage speed for
journey?

Answer:
125 m
Explanation:
Intial velocity of the car , u = 36 km/h
= 36× 1000m
__________=10m/s
3600s
Final velocity, v = 54 km/h = 54×1000m
__________=15m/s
3600s
Time at which the speed increases,t=10s
Acceleration a=?
Distance travelled by the car in time t,s=?
(i) using the first equation of motion,
Acceleration , a = v-u/t=15-10/10=0.5ms-²
(ii) using the second equation of motion,
Distance travelled, s= ut + 1/2 at ²
=10×10+1/2×(0.5)×(10)²
s=100+25=125m
