Question

please help me with the answer of math given in photo please fast...​

Answer 1

Answer:

Explanation:As we know force=mass×acceleration

Slope of a graph is y coordinate/x coordinate so for above we can do the following

(100)/1000×(20÷5)=0.4N

Answer 2

Answer:

force acting on the body

= 0.4 N

Step by step explanations:

Here in the graph

initial velocity at t = 0

= 0 m/S

and final velocity at t = 5 s

= 20 m/s

so,

acceleration of the body

= (v - u) /t

where,

v = final velocity

u = initial velocity

t = time taken

so,

acceleration = (20 - 0)/5

= 20/5

= 4 m/s²

now,

force acting on the body

= mass × acceleration

given mass = 100 g

= 0.1 kg

acceleration = 4 m/s²

so,

force = 0.1 kg × 4 m/s²

= 0.4 kgm/s²

= 0.4 N

so

force acting on the body

= 0.4 N
