27. A small block of mass \( m \) is pressed against a horizontal spring fixed at one end to compress the spring through \( 5.0 cm \). When released the block moves horizontally till it leaves the spring. Where will it hit the ground at a distance \( 2 m \) below the slab? ( \( k=100 N / m , m=100 g ) \). 6

Question

pls tell me book name from which this question has been taken? 

Answer 1

Given,

m = 100g = 0.1kg

x = 5cm = 0.05m

k = 100N/m

When the body leaves the spring, let the velocity v.

For the projectile motion,

Downward direction is taken as negative

θ = 0°, y = -2

Now, y = (u sin θ)t - 1/2gt²
