Question

physics class 9 solve it fastly​

Answer 1

Answer:

Given-

v=0

u=54kmph

t=5 second

First we convert 54kmph to m/sec.

=> 54kmph = 15m/sec

(a) Now we use the first equation of motion.

=> v=u+at

=> 0= 15 + a*5

=> -15 = a*5

=> a= -5m/s^2

Find the answer of (b) & (c) in the image attached.
