<span>We know that v = u + at
He stops when the speed is zero; therefore
0 = 15 - 3.35 t
t = 4.48
It takes 4.48 seconds after the driver turns on the brake for him to stop.
We know
s = ut + (1/2)at</span>²<span>
s = 15*4.48 - *(1/2)(3.25)(4.48)</span>²<span>
s = 33.4 meters
The distance he travels before applying the brakes is:
s = 0.21 * 15
s = 3.15 m
The total distance he travels is:
3.15 + </span>33.4 = 36.55 meters
He will be able to stop in time.
A microscope is used for the purpose of magnification of an object which is usually very minute - so much so that it is not easy to be seen with the naked eye. If a mount slide contains the word <em>lens</em> which is easily readable with the naked eye and if this slide is kept under a microscope, the text will appear:
- From left to right that is in the same original direction as it was positioned on the slide.
- Highly magnified which may make it illegible to be read using the microscope.
-- The volume of water is (1.5 m² x 7 m) = 10.5 m³
10.5 m³ = 10,500 liters
Water mass = (10,500 liters) x (1 kg/liter) = 10,500 kg.
-- "Force of gravity on the water"
= Weight of the water = (10,500 kg) x (9.8 m/s²) = 102,900 newtons
-- Pressure on the bottom of the tank =
(102,900 newtons) / (1.5 m²)
= 68,600 nt/m² = 68,600 pascal .
He's accelerating at 3 m/s² .
That means his speed is increasing by 3 m/s every second.
At the end of 8 seconds, his speed is (8 x 3 m/s) = 24 m/s .
He's been moving south for the whole 8 seconds.
So at the end of that time, his velocity is
24 m/s south .
