A body of mass 1 kg is thrown vertically up with an initial speed of 5

1.	A body of mass 1 kg is thrown vertically up with an initial speed of 5 m s-1. What is the magnitude and direction of force due to gravity acting on the body when it is at its highest point? Take G = 9.8 n kg-1
Answer» Mass of body= 1 kg Initial speed = 5 m/s Acceleration due to gravity = 9.8 N/kg (vertically downwards) Force= mass x acceleration =1 × 9.8 = 9.8N = 1 kgf 9.8 N or 1 kgf force acts vertically downwards.

Answer»

Mass of body= 1 kg

Initial speed = 5 m/s

Acceleration due to gravity = 9.8 N/kg (vertically downwards)

Force= mass x acceleration

=1 × 9.8 = 9.8N = 1 kgf

9.8 N or 1 kgf force acts vertically downwards.
