A 3000 kg truck travelling at 50km/hr strikes a stationary 1000 kg car, locking the two vehicles together, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.

We may use the concept of conservation of momentum to calculate the final velocity of the two vehicles after the collision.

The total initial momentum (P_initial) is given by:

P_initial = (mass of truck) * (initial velocity of truck) + (mass of car) * (initial velocity of car)

P_initial = (3000) * (50) + (1000) * (0)

The velocity:

Vt = 50 * (1000/3600) = 13.9 m/s

Vc = 0 = 0 m/s

P_initial = (3000) * (13.9) + (1000) * (0 )

P_initial = 41700 kg·m/s

P_initial = P_final

41700 kg·m/s = (3000 kg + 1000 kg) * Vf

41700 kg·m/s = 4000 kg * Vf

Now Vf:

Vf = 41700 kg·m/s / 4000 kg

Vf ≈ 10.43 m/s

Therefore, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.

Explanation:

acceleration is 2 m/s^2

v-u/t

distance travelled is 30.25 meter

(v^2-u^2)/2a

11*11/2*2

121/4

30.25 m

The acceleration of the bicyclist is 2 m/s² and the total distance covered is 30.25 meters.

We have a bicyclist.

We have to calculate the acceleration and the total distance travelled by the bicyclist.

The three equations of motion are -

v = u + at

S = ut + [tex]\frac{1}{2}[/tex] a[tex]t^{2}[/tex]

v² - u² = 2aS

According to the question -

u = 0 m/s

v = 11 m/s

t = 5.5 s

Therefore -

For acceleration -

v = u + at

On solving -

11 = 0 + 5.5 a

5.5a = 11

a = 11 / 5.5 = 2 m/s²

For total distance covered -

S = ut + [tex]\frac{1}{2}[/tex] a[tex]t^{2}[/tex]

On solving -

S = 0 + 0.5 x 2 x 5.5 x 5.5 = 30.25 meters.

Hence, the acceleration of the bicyclist is 2 m/s² and the total distance covered is 30.25 meters.

Answer:

true..........................

Speed and velocity use the same formula for calculations. However, an object can have a different average speed and average velocity because of displacement. This is true statement.

As a vector quantity with both magnitude and direction, velocity has both. This term refers to the speed at which an object is moving or shifting positions.

Since speed is a scalar quantity, it lacks direction. It indicates the rate of a moving thing. When a particle's speed is high, it indicates that it is travelling quickly, and when it is low, it indicates that it is going slowly.

The displacement of a body during a period of time divided by the passage of time yields the average velocity of the body during that period.

The distance travelled by a body in a given amount of time, divided by the amount of time, is the body's average speed.

Answer:

Explanation:

The average speed of the train was 5.33  meter/second.

Speed is distance travelled by the object per unit time. Due to having no direction and only having magnitude, speed is a scalar quantity With SI unit meter/second.

Given parameters:

Distance travelled by the train is: d = 80 meters.

Time  taken by the train: t = 15 seconds.

Hence,  the average speed of the train =

total distance travelled/total time taken

= 80 meters/ 15 seconds.

= 5.33  meter/second.

Gaya balok karena beratnya diberikan oleh

Kondisi dimana balok mulai bergerak adalah ketika gaya balok akibat beratnya sama dengan gaya gesek pada balok.

[tex]mg\sin\theta=\mu mg\cos\theta\\\Rightarrow \mu=\dfrac{mg\sin\theta}{mg\cos\theta}\\\Rightarrow \mu=\tan\theta\\\Rightarrow \mu=\tan40^{\circ}\\\Rightarrow \mu=0.84[/tex]
