Question

A car of 1000 kg moving with a velocity of 18 km/hris stopped by the break force of 1000N. Find distance covered by it before coming to rest​

Answer 1

Answer:

m=1000kg

u = 18kmph = 5m/s

v = 0

F = ma = 1000a

Given F = 1000N

=> 1000 = 1000a

=> a = 1m/s²

Now v² - u² = 2as

s = v² - u² / 2a

= -25/2

= 12.5 m (ignoring negative symbol as its of the direction)
