Question

An object of mass 10 kg is accelerated upward at 2 m/s2. What force is required?

Answer 1

Answer:

The force required to accelerate the object upward direction is 20 N. Given m = 10 kg and . F = 20 N. Thus, the force required to accelerate the object upward direction is 20 N.

Answer 2

The force required to accelerate the object of mass 2 kg upwards is 20 N.

Given,

Mass of the object=10 kg

Acceleration of the object=$2 \frac{m}{s^{2} }$.

To find,

force required.

Solution:

Force is an external agent capable of changing the state of a body(rest or motion). The S.I. unit of force is Newton(N).

Acceleration is the rate of change of velocity of an object. The S.I. unit of acceleration is $\frac{m}{s^{2} }$.

Force is calculated as:

F=m x a

where,

F-force applied

m-mass of the body

a-acceleration of the body.

F=10 x 2

F=20 N.

The force required to accelerate the object upwards is 20 N.
