<span>It also doubles
The gravitational force between two masses is expressed as:
F = G*m1*m2/r^2
where
F = Force between the two masses
m1 = Mass of object 1
m2 = Mass of object 2
r = distance between centers of object 1 and object 2
G = Gravitational constant
The exact values of G, m1, m2, and r don't matter since all except for m1 is held constant. And when m1 suddenly doubles, the force attracting the two object to each other also doubles.</span>
Answer:
False
Explanation:
The steel ball and the wooden ball do not have the same force acting on them because their masses are different. But, they have the same acceleration which is the acceleration due to gravity g = 9.8 m/s².
Using the equation of motion under freefall, s = ut +1/2gt². Since u = 0,
s = 1/2gt² ⇒ t = √(2s/g)
Since. s = height is the same for both objects, they land at the same time neglecting air resistance.
Answer:
50m/s.
Explanation:
Let's take acceleration as A and speed as S:
A = 5m/s²
S = A × 10s = 5 × 10 = 50m/s
The answer is 50m/s.
Answer
given,
x(t) = A t + B t²
A = -4.1 m/s
B = 5.4 m/s²
a) velocity of the particle is equal to the differentiation of Position w.r.t. time
the above equation gives the function of velocity.
b) time at which velocity of particle is zero
v = -4.1 + 10.8 t
inserting v = 0 and calculating v
0 = -4.1 + 10.8 t
10.8 t = 4.1
t = 0.38 s
time at which velocity is zero is equal to 0.38 s.
