Answer:
Weight of the object will be 195.6 N
Explanation:
We have given mass of the object m = 20 kg
And acceleration due to gravity at any location is given
We have to find the weight of the object in N at the location where value of acceleration due to gravity is
Weight of the object is given by W = mg , here W is weight , m is mass and g is acceleration due to gravity
So weight W = 20×9.78 = 195.6 N
So weight of the object will be 195.6 N
Answer:
Explanation:
Use the one-dimensional equation
which says that the final velocity of an object is equal to the object's initial velocity plus its acceleration times time. We are looking for time. That means the equation looks like this:
0 = 30 + (-4)t and
-30 = -4t so
t = 7.5 sec
