Pls help me solve this<br><br><br><br>​

Answer:

a) The uniform velocity travelled by the car is 10 meters per second.

(Point b has been erased by the user)

c) The distance travelled by the car with uniform velocity is 100 meters.

Explanation:

a) Calculate the uniform velocity travelled by the car:

The uniform velocity is the final velocity (v), in meters per second, of the the uniform accelerated stage:

v = v_{o} + a\cdot t (1)

Where:

v_{o} - Initial velocity, in meters per second.

a - Acceleration, in meters per square second.

t - Time, in seconds.

If we know that v_{o} = 0\,\frac{m}{s}, a = 2\,\frac{m}{s^{2}} and t = 5\,s, then the uniform velocity is:

v = 0\,\frac{m}{s} + \left(2\,\frac{m}{s^{2}} \right)\cdot (5\,s)

v = 10\,\frac{m}{s}

The uniform velocity travelled by the car is 10 meters per second.

(Point b has been erased by the user)

c) The distance travelled by the car (\Delta x), in meters, with uniform velocity is calculated by the following kinematic expression:

\Delta x = v\cdot t (2)

If we know that v = 10\,\frac{m}{s} and t = 10\,s, then the distance travelled is:

\Delta x = \left(10\,\frac{m}{s} \right)\cdot (10\,s)

\Delta x = 100\,m

The distance travelled by the car with uniform velocity is 100 meters.

Aunt Mary needs to hang a picture in her bedroom. She uses a hammer to drive the nail into the wall. Find the force exerted by t
Cerrena [4.2K]

t = time of contact of hammer with the nail = 0.4 sec

I = impulse exerted by the hammer on the nail = 32 N s

F = force applied by the hammer on the nail

we know that , impulse is given as

I = F t                  where I = impulse , F = force , t = time

hence the impulse of hammer on nail is given as

I = F t

inserting the values

32 Ns = F (0.4 sec)

F = 32/0.4

F = 80 N

hence the force exerted by the hammer comes out to be 80 N
