A 50 kg mass is lifted 2 m in 0.5 seconds.
1 answer:
The weight of the mass is 490 N
Explanation:
The weight of an object is equal to the gravitational force exerted by the Earth on the object, and it is given by the equation
where
m is the mass of the object
g is the acceleration due to gravity
For the object in this problem, the mass is
m 50 kg
While on the Earth's surface, the value of the acceleration of gravity is
Therefore, the weight of the object is:
