Gregor Mendel finished his pea plant experiments in 1863 and published his results in 1866. However, few scientists saw Mendel's

Explanation:
The given data is as follows.
F = 3.2 N, m = 18.2 kg,
t = 0.82 sec
(a) Formula for impulse is as follows.
I = Ft =
Ft =
or,
Putting the given values into the above formula as follows.
=
= 0.144 m/s
Therefore, final velocity of the mass if it is initially at rest is 0.144 m/s.
(b) When velocity is 1.85 m/s to the left then, final velocity of the mass will be calculated as follows.
Ft =
or,
=
= -1.705 m/s
Hence, we can conclude that the final velocity of the mass if it is initially moving along the x-axis with a velocity of 1.85 m/s to the left is 1.705 m/s towards the left.
Answer:
Two objects will have the equal velocities but the forces on both of them will not be equal. The equal velocities of these objects are due to their equal acceleration.
Explanation:
From the newton's equation
so here we can say that velocity does not depends on the mass.
The acceleration of both objects will be same but not the forces because
F = Ma
As the force is depending on the mass so it will not be the same for both objects.
