What is the velocity of a rocket if it travels a distance of 2400 m in 3 s?

Physics

SOVA2 [1]3 years ago
6 0

Answer:

v = 800 m/s

Explanation:

Given that,

Distance, d = 2400 m

Time, t = 3 s

We need to find the velocity of a rocket. Distance covered per unit time equals velocity. So,

v=\dfrac{d}{t}\\\\v=\dfrac{2400\ m}{3\ s}\\\\v=800\ m/s

So, the velocity of the truck is 800 m/s.

A stone is thrown towards a wall with an initial velocity of v0=19m/s and an angle = 71 with the horizontal, as illustrated in t
HACTEHA [7]

Answer:

(a) 2.85 m

(b) 16.5 m

(c) 21.7 m

(d) 22.7 m

Explanation:

Given:

v₀ₓ = 19 cos 71° m/s

v₀ᵧ = 19 sin 71° m/s

aₓ = 0 m/s²

aᵧ = -9.8 m/s²

(a) Find Δy when t = 3.5 s.

Δy = v₀ᵧ t + ½ aᵧ t²

Δy = (19 sin 71° m/s) (3.5 s) + ½ (-9.8 m/s²) (3.5 s)²

Δy = 2.85 m

(b) Find Δy when vᵧ = 0 m/s.

vᵧ² = v₀ᵧ² + 2 aᵧ Δy

(0 m/s)² = (19 sin 71° m/s)² + 2 (-9.8 m/s²) Δy

Δy = 16.5 m

(c) Find Δx when t = 3.5 s.

Δx = v₀ₓ t + ½ aₓ t²

Δx = (19 cos 71° m/s) (3.5 s) + ½ (0 m/s²) (3.5 s)²

Δx = 21.7 m

(d) Find Δx when Δy = 0 m.

First, find t when Δy = 0 m.

Δy = v₀ᵧ t + ½ aᵧ t²

(0 m) = (19 sin 71° m/s) t + ½ (-9.8 m/s²) t²

0 = t (18.0 − 4.9 t)

t = 3.67

Next, find Δx when t = 3.67 s.

Δx = v₀ₓ t + ½ aₓ t²

Δx = (19 cos 71° m/s) (3.67 s) + ½ (0 m/s²) (3.67 s)²

Δx = 22.7 m

Isla’s change in velocity is 30 m/s, and Hazel has the same change in velocity. Which best explains why they would have differen
lyudmila [28]

Acceleration  =  (change in velocity) / (time for the change) .

They may have had the same change in velocity, but if the changes
happened in different lengths of time, then their accelerations were
not the same.
