Question

A particle is thrown vertically upwards with velocity 20 m/s. The distance travelled by the particle in first 3 seconds is?

Answer if you know it’s full solution......

Answer 1

Answer:

15.9 m

Step-by-step explanation:

initial velocity, u=20 m/s

time, t=3 sec

Here acceleration due to gravity, g= -9.8m/s^2 =a

Here, negative sign tells that the direction of motion of the particle and acceleration due to gravity are opposite to each other.

As we know that,

s=ut+1/2at^2

=20*3+1/2*(-9.8)*3*3

=60-44.1

=15.9 m
