Question

an asronaut on a planet having no atmosphere throws a stone of mass m vertically upwards with velocity 10 m/s. It reaches maximum height of 10 m. If another stone of mass 2m is thrown upwards with velocity 20 m/s, the maximum height reached will be

Answer 1

Answer:

2.5m

Explanation:

M1V1H1=M2V2H2

• m1=m, m2=2m, v1=10m/s, v2=20m/s, h1=10, h2= ?

h2= 100×m/20×2m= 2.5m
