At the given erro in angle, the error in the measurement of sin 90 degrees would be 0.001.

<h3>Percentage error</h3>

The percentage error of any measurement is obtained from the ratio of the error to the actual measurement.

The error of sin 90 degrees is calculated as follows;

sin 90 = 1

error in measurement = sin(90 - 0.5)

error in measurement = sin(89.5) = 0.999

<h3>Error in sin 90 degrees</h3>

Error in sin 90 degrees = 1 - 0.999

Error in sin 90 degrees = 0.001

Thus, at the given erro in angle, the error in sin 90 degrees would be 0.001.

At the instant a traffic light turns green, a car starts with a constant acceleration of 1.3 m/s2. At the same instant a truck,

Bas_tet [7]

Answer:

(a) Distance traveled = 75.3846 m

(b) Velocity of car at that instant will be 14 m/sec

Explanation:

We have given acceleration of the car $a=1.3m/sec^2$

Initial velocity of the cart u = 0 m/sec

(a) According to second equation of motion we know that $s=ut+\frac{1}{2}at^2$

So distance traveled by car $s_c=0\times t+\frac{1}{2}\times 1.3t^2=0.65t^2$

As the truck is moving with constant speed

So distance traveled by truck $s_t=ut=7t$

As the truck overtakes the car

So $s_c=s_t$

$0.65t^2=7t$

$t=10.769sec$

So distance traveled $s_c=s_t=7\times 10.769=75.3846m$

(b) From second equation of motion we know that v = u+at

So v = 0+1.3×10.769 = 14 m /sec

A car is behind a truck going 25m/s on the highway. the car's driver looks for an opportunity to pass, guessing that his car can

Misha Larkins [42]

Velocity of cars = 25 m/s

Distance the car has to cover for passing truck = 40m

Distance of passing spot from the car coming from opposite direction = 400- 40 =360 m

Time available for the car to pass truck of 20 m length = Distance of passing spot from the car coming from opposite direction/relative velocity between cars

Time = 360/50 = 7.2 seconds

Suppose the truck is moving at the same speed of car.

Distance traveled by car compared to truck is given by the expression

S = ut + $\frac{1}{2} at^2$ , where S is the distance traveled, u is the initial velocity a is the acceleration and t is the ime taken.

In this case u = 0, t = 7.2 s, a = 1 m/ $s^2$

So distance traveled by car in 7.2s compared to truck = 0*7.2+ $\frac{1}{2} *1*7.2^2$

So, S = 0+ 25.92 = 25.92 m

So car will travel only travel 25.92 m

In order to overtake it needs to travel 40m. So don't attempt to pass the truck.
