Answer:

Option(a) All of the above;

Explanation:

In relation to physics, force can be defined as any interaction between two bodies or objects that will change their motion. In simpler terms force refers to push/pull of a body with mass m that results in change of velocity or the acceleration a.

The concept of force can be better studied with the help of Newton’s three laws of motion. In it, he explained the nature of action of forces under normal condition

A stone is dropped from a height of 49m and simultaneously another ball is thrown upward from the ground with a speed of 40m/s.

Lilit [14]

Answer:

S1 = 1/2 g t^2 distance stone falls in time t

S2 = Vy t - 1/2 g t^2 distance thrown stone rises in time t

H = 49 = S1 + S2 = Vy t

t = 49 / 40 sec time when stones meet

Check:

Stone 1 falls: 1/2 g t^2 = 1/2 * 9.8 * (49 / 40)^2 = 7.35 m

Stone 2 rises : 40 * (49 / 40) - 1/2 * 9.8 (49 / 40)^2 = 41.65 m

The chart show the masses and velocities of two colliding objects that stick together after a collision.

finlep [7]

Answer:

1,500 kg.m/s

Explanation:

First, arrange the information in a table:

Object Mass (kg) Velocity (m/s)

A 200 15

B 150 - 10

After the collision, the two objects are stick together, thus you talk aobut one object and one momentum.

According to the law of convervation of momentum, the momentum after the collision is equal to the momentum before the collision.

Momentum before the collision, P₁:

$P_1=m_{A,1}\times v_{A,1}+m_{B,1}\times v_{B,1}$

$P_1=200kg\times 15m/s+150kg\times (-10m/s)\\\\ P_1=3000kg.m/s-1500kg.m/s=1500kg.m/s$

Momentum after the collision:

As stated, it es equal to the momentum before the collision: 1,500 kg . m/s
