Question

The velocity-time graph of a coin moving on a table is shown in following figure. The mass of the
coin is 10 g. How much force does the table exert on the coin to bring it to rest?

Answer 1

Explanation:

a=v-u/t1-t2

=0-24/0-8

=-24/-8

=3 m/s^2

f=mass into acceleration/1000

=10 into 3/1000

=3/100

=0.03

Answer 2

Answer:

a little dirty but fine...........
