Question

A particle of mass 2kg is thrown upwards with a speed of 10m/s. It returns the same point with a speed of 8m/s. If the air resistance is constant, find the maximum height reached by the particle.

a) 2.1m
b) 3.1m
c) 4.1m
d) 5m​

Answer 1

Answer:

4•1 m is the maximum height riched by the particle

Answer 2

Answer:

hi

solutions

for u=10m/s

S=v^2-u^2/2g

0-10^2/-2x10

5m

if (g=10)
