Question

solve the following:
1. a man of 600 n climbs up a height of 400 m. calculate is the work done by him

2. a box is being pushed by applying a force of 200 n. if work done is 300 j, what is the displacement of the box from the direction of force.

3. an athlete weighing 50 kg is running at a constant speed of 10 m/s. what is his kinetic energy

Answer 1

Answer:

1)240000j

2)1.5m

3)250j

Explanation:

for 1&2 use work=force×dis.
