Answer:

It is called a collision.

Explanation:

When two objects bump into each other, this is called a collision. In physics, a collision doesn't have to involve an accident (like two cars crashing into each other), but can be any event where two or more moving objects exert forces on each other for a short period of time.

Answer:

Given: Vi = 382 km/h, Vf = 0 km/h, Mc = 705 kg, Md = 65 kg, Δt = 12

Required: Δx

F = Δp / Δt

  = \frac{(Mc+Md)Vf-(Mc+Md)Vi}{t} \\\\= 6.81 * 10x^{3} N [left]\\\\x=\frac{1}{2} (Vi+Vf)\\ \\ = 637m[right]

An airplane starts its takeoff by moving at 1.7 m/s. The plane must then accelerate at 3.0 m/s2 for the next 30s to reach its fi
otez555 [7]

Answer:

The distance is 1.4 km.

Explanation:

Given that,

Initial velocity u= 1.7 m/s

Accelerate a= 3.0 m/s²

Time = 30 s

We need to calculate the distance

Using equation of motion

s= ut+\dfrac{1}{2}at^2

Where, u = initial velocity

a = acceleration

t = time

Put the value in the equation

s=1.7\times30+\dfrac{1}{2}\times3.0\times(30)^2

s=1401\ m

s=1.4\ km

Hence, The distance is 1.4 km.
