A projectile is launched at an angle above the
erica [24]
If we neglect friction/air resistance, then the horizontal component
doesn't change, and the vertical component becomes (9.8 m/s downward)
greater each second thanks to gravity.

So, after 2 seconds, the horizontal component is still 40 m/s, and the
vertical component is (30 - 2·9.8) = 10.4 m/s upward.

Choice #1 says this.

Two trains, each having a speed of 28 km/h, are headed at each other on the same straight track. A bird that can fly 60 km/h fli
Semenov [28]

Answer:

The value is D =  70.71 \ km

Explanation:

From the question we are told that

The speed of each train is v =  28 \  km/h

The speed of the bird is v_1 =  60 \  km/h

The distance between the trains is d =  66 \  km

Generally the time taken before the collision occurs is mathematically represented as

t =  \frac{d}{2 * v}

=> t =  \frac{66 }{2 *  28}

=> t = 1.18 \  h

The total distance covered by the bird is mathematically represented as

D =  v_1 *  t

=>   D =  60 * 1.18

=>   D =  70.71 \ km
