a) KE=energy required to make them move=1800J
b) KE=1/2*mv^2, so J
Explanation:
We have,
According to attached figure, the height of the inclined plane is 60 m and force acting on the block is 10 N. It is required to find the work must be done against gravity to move it to the top of the incline. The work done is given by :
W = mgh
or
Hence, the correct option is (A) "600 J".
