(a) The compression of the spring is 0.074 m.

(b) The potential energy of block will be converted to elastic potential energy of the spring when the block comes to rest.

<h3>Compression of the spring [ x ]</h3>

The compression of the spring is calculated as follows;

F = kx

mg = kx

x = mg/k

where;

  • m is mass of the object
  • k is the spring constant

x = (3 x 9.8) / (400)

x = 0.074 m

<h3>Motion of the block</h3>

Based on the principle of conservation of energy, the potential energy of block will be converted to elastic potential energy of the spring when the block comes to rest.

A car is traveling at 21.0 m/s. It slows to a stop at a constant rate over 5.00s. How far does the car travel during those 5.00
Doss [256]

Answer:

d = 105 m

Explanation:

Speed of a car, v = 21 m/s

We need to find the distance traveled by the dar during those 5 s before it stops. Let the distance is d. It can be calculated as :

d = v × t

d = 21 m/s × 5 s

d = 105 m

So, it will cover 105 m before it stops.
