A car passes point “A” and then 120 meters later. It’s velocity was measured 21 m/s. If it’s acceleration was constant at 0.853
Norma-Jean [14]

Recall that

{v_f}^2-{v_i}^2=2a\Delta x

where v_i and v_f are the initial and final velocities, respecitvely; a is the acceleration; and \Delta x is the change in position.

So we have

\left(21\dfrac{\rm m}{\rm s}\right)^2-{v_i}^2=2\left(0.853\dfrac{\rm m}{\mathrm s^2}\right)(120\,\mathrm m)

\implies v_i\approx\boxed{15.4\dfrac{\rm m}{\rm s}}

(Normally, this equation has two solutions, but we omit the negative one because the car is moving in one direction.)

Someone please please please help me with this. I’ll give u whatever rating u want
tensa zangetsu [6.8K]

The vertical forces add up to zero.

The net force on the object is 60N to the right.

F = m • a

60N right = (10kg) • (a)

a = (60N right) / (10kg)

a = 6 m/s^2 to the right

Multi-engine Commercial would be nice.
