Question

pls ans it......................​

Answer 1

Answer:

Step-by-step explanation:

300kg,15ms,100kg

Answer 2

Answer:

uniform velocity is 30 m s‐¹

time to stop 2s

force is 1500N

mass= p/v=100

a)momentum = p=mv

:p=30×100=3000kgm/s

b)radiation produce in momentum of car=30÷2=15m/a

c)mass of car will be 100

hope you can understand
