The final velocity is of the car is 35ms^{-1}.

<u>Explanation:</u>

The car initially moves in the velocity 20 ms^{-1}. It then accelerated by 3ms^{-2} for 5 seconds.

The formula to find final velocity, v_f=v_i+a(t).

v_i:  initial velocity of the car.

a:  acceleration rate.

t:  time.

v_f:  final velocity  

From the given information,

v_i= 20ms^{-1}.

a=3ms^{-2}.

t= 5s.

v_f=20+3(5).

=20+15.

=35ms^{-1}.

∴The final velocity of the moving car is 35ms^{-1}.

If an object accelerates from rest, what will its velocity be after 1.3 s if it has a constant acceleration of 9.1 m/s^2?
HACTEHA [7]

\text{Given that,}\\\\\text{Initial velocity,} ~v_0 = 0~ \text{m~s}^{-1}\\\\\text{Time,  t = 1.3~sec}\\\\\text{Acceleration, a = 9.1 m s}^{-2}\\\\\\\\\text{Velocity,}\\\\v = v_0  +at\\\\\implies v = 0 + 9.1 \times 1.3 = 11.83~~ \text{m~s}^{-1}

A plane traveling horizontally at 120 ​m/s over flat ground at an elevation of 3610 m must drop an emergency packet on a target
allsm [11]

Answer:

Explanation:

Horizontal displacement

x = 120 t

Vertical position

y = 3610 - 4.9 t²

y = 0 for the ground

0 = 3610 - 4.9 t²

t = 27.14 s

This is the time it will take to reach the ground .

During this period , horizontal displacement

x = 120 x 27.14 m

= 3256.8 m

So packet should be released 3256.8 m before the target.
