Answer 1

Answer:

1. Force : -10⁵N

2. Time : 0.0001s

Answer 2

Answer:

1) F = -10⁵N

2) t = 0.0001 s

Explanation:

given,

m= 10g = 10^(-2) kg

u = 10³m/s

v= 0

s = 5cm = 0.05m

Now ,

1) using v²-u² = 2as

we get=> 0² - (10³)² = 2(a)(0.05m)

=> -10⁶ = 0.1a

=> a = -10⁷ m/(s²)

F= ma = 0.01× (- 10⁷ )

=> F = - 10⁵ N

2) using, v= u + at

we get, => 0 = 10³ + (-10⁷) t

=> 10⁷ t = 10³

=> t = 10^(-⁴) = 0.0001s
