Question

a force of 600 dynes acts on a glass ball of mass 200g for 12 seconds. If initially the ball is at rest find - 1. final velocity
2. distance covered​

Answer 1

Answer:

velocity=36 cm/s

distance= 216 cm

Explanation:

F=ma

600=200a

a=3 cm/s²

since u=0,

v=u+at

=3×12

=36 cm/s

using equation of motion,

S=1/2at²

=1/2×3×144

=3×72

=216 cm
