A 2 kg block is on a horizontal surface. A horizontal force is applied by a person to the block to pull it on the surface with a
Agata [3.3K]

Answer:

work done = 500 J

option e is correct

Explanation:

given data

mass = 2 kg

acceleration = 2 m/s

coefficient of kinetic friction = 0.3

block D = 50 m

to find out

work

solution

we know that work done is

work done = f × d    ...........1

here f is force and d is block i.e 50 m

so here

force , f - k mg  =ma

f = 2 ( 2 + 0.3 ×10 )

f = 10 N

so from equation 1

work done =  f × d

work done = 10 × 50

work done = 500 J

option e is correct

A body moving with an initial velocity of 30m/s accelerates uniformly at the rate of 10m/s . what is the distance covered during
nikdorinn [45]

Answer:

The distance covered by the body is, S = 800 m

Explanation:

Given data,

The initial velocity of the body, u = 30 m/s

The acceleration of the body, a = 10 m/s²

Let the time period of travel be, t = 10 s

Using the II equations of motion,

                       S = ut + ½ at²

Substituting the given values,

                        S = 30 x 10 + ½ x 10 x 10²

                         S = 800 m

Hence, the distance covered by the body is, S = 800 m
