A car has a mass of 850 kg. By pushing on the car, Evan increases its speed

Dmitry_Shevchenko [17]

Answer:

I=1,2•10³ kg•m/s

Explanation:

v¹=3.5m/s

vf=5m/s

v=5-3.5=1.5m/s

I=p

I=mv=850•1.5=1275 kg•m/s=1,2•10³ kg•m/s

. An object has a position given by ~r(t) = [3.0 m − (4.00 m/s)t]ˆı + [6.0 m − (8.00 m/s2 )t 2 ]ˆ , where all quantities are in

kupik [55]

Answer:

Explanation:

The position is $r(t) = [3.0 \text{ m} - (4.00 \text{ m/s})t]\hat{i} + [6.0 \text{m} - (8.00 \text{ m/s}^2 )t^2 ]\hat{j}$ .

The velocity is the first time-derivative of r(t).

$v(t) = \dfrac{d}{dt}r(t) = -4.00\,\hat{i} -16t\,\hat{j}$

The acceleration is the first time-derivative of the velocity.

$a(t) = \dfrac{d}{dt} v(t) = -16\hat{j}$

Since a(t) does not have the variable t, it is constant. Hence, at any time,

$a = -16\hat{j}$

Its magnitude is 16 m/s².

Masja [62]

Answer:

W = 5586[J]

Explanation:

Work in physics is defined as the product of force by a distance.

$W=F*d$

where:

W = work [J]

F = force = m*g [N]

m = mass = 300 [kg]

g = gravity acceleration = 9.81 [m/s²]

d = distance = 1.9 [m]

Now replacing:

$W=m*g*d\\W=300*9.81*1.9\\W=5586[J]$
