Question

Q14 a) .Calculation of acceleration of the car : ( For motion from A to B ) initial velocity of the body at

time t1 ,u = 5m/s.

b). Find the value of distance covered by car​

Answer 1

Answer:

a) -5

b) 2.5m

Explanation:

Keys:

u= initial velocity

v=final velocity

a=acceleration

r=retardation

t=time

s=distance

u = 5m/s

t=1s

v =0  

a=v-u \t

a= 0-5/1

a= -5 or r= 5

b)   s=ut+1/2at²     [ Second Equation of motion ]

s= 5×1+1/2×-5×1×1

s=5+(-2.5)

s=2.5 m
