Question

solve these numericals,and follow me I will also follow you​

Answer 1

Answer:

we know that

work= force*displacement

=5 * 9.8 *2 (here we don't have value of a for force so let it gravitational force i.e, 9.8)

so answer will be 98 joule

Answer 2

Explanation:

1. Work = mass × distance

            = 5 ×10 × 2

            = 100 joules

2. Kinetic energy = 1/2m$v^{2}$

                             = 1/2 × 2 × 4

                             = 4 joules
