Question

A force of 6.0 Newtons is applied to a block at rest on a horizontal frictionless surface over a 7.0 meter span. How much energy is gained by the block?

a) 3.0 m/s

b) 7.0 m

c) 42 J

d) 6.0 N

Answer 1

C. 42J

Step-by-step explanation:

Given data

Force= 6N

Distance= 7m

Required

The energy gained

Work= Force* Distance

Work= 6*7

Work= 42Joules

Hence the option c 42J is correct
