An auto race takes place on a circular track. A car completes one lap in a time of 18.0 s, with an average tangential speed of 4

eduard

Answer:

(A) 0.3488 rad/sec

(B) 124.246 m

Explanation:

We have given car completes one revolution in 18 sec'

So time period T= 18 sec

Tangential speed v = 43.4 m/sec

(A) Angular velocity is given by $\omega =\frac{2\pi }{T}=\frac{2\times 3.14}{18}=0.3488rad/sec$

(B) Tangential velocity is given v = 43.4 m /sec

We know that $v=\omega r$

$r=\frac{v}{\omega }=\frac{43.4}{0.3488}=124.426m$

A sample has a density of 30 g/ml. there is 60 ml of this substance.how much does it weigh?

aleksandrvk [35]

If each mL has 30 grams of the substance in it, then 60 mL have 1800 grams of mass in them. the weight of 1,800 grams of mass on Earth is (1.8 kg) x (9.8 m/s^2) = 17.6 newtons.

A squirrel jumps down from a tall tree. Assuming the squirrel is in free fall, how far will it have fallen in 1.5 seconds?

snow_tiger [21]

D = 1/2gt^2 <-- free fall formula

d = (0.5)(9.81)(1.5^2)
d = 11.03625
d = 11.04 m

hope this helps and have a great day :)
