Question

the car acceleration uniformly from heating kilometre per hour to 36 km per hour in 5 seconds calculate acceleration by car
​

Answer 1

Acceleration = Change in Velocity/Time

Change in Velocity = 36-18 = 18 km/h=5 m/s

Time= 5 Seconds

Acceleration = 5/5= 1 m/s2

Equation of motion,s=ut+(1/2)at2

u=18 km/h=5 m/s

t=5 s

a=1 m/s2

s= (5*5)+(1/2*1*5*5)

s=25+12.5 i.e., s=37.5 m

hope it will help you ❣️❣️

Answer 2

Answer:

Hey Mate ✌️

Initial speed = u = 18 km/hr = 5 m/s

Final sped = v = 36 km/hr = 10 m/s

acceleration a = (v-u)/t = (10-5)/5 = 1 m/s2

Distance travelled S = u t + (1/2) a t2 = 5×5 + (1/2)×1×52 = 37.5 m

hope it will be helpful ✌️
