Question

A ball is hit with a speed of 10 metre per second in upward direction if mass of a ball is 500 gram then calculate the height attained by a ball​

Answer 1

Answer:

5 metre

Explanation:

hope it will help

Answer 2

Given, mass of the ball, m=5kg

Speed of the ball, v=10m/s

(a) Initial kinetic energy of the ball,

E

k

=

2

1

mv

2

=

2

1

(5)(10)

2

=250J

When the ball reaches the highest point, its kinetic energy becomes zero and

the entire kinetic energy is converted into its potential energy.

∴E

p

=250J

(b) If h is the maximum height attained by the ball,

E

p

=mgh or mgh=250J

or h=

mg

250

=

(5)(10)

250

=5m
