What is the distance covered when the speed is 960km/hr and time is 1 hour and 50 minutes?

OLEGan [10]

The distance is 1760 km

The speed is 960 km hour I.e 960 divide by 60 = 16 km/minute
hence in time 1 hour 50 minutes I.e 110 minutes
distance travelled is 110 - 16 = 1760 km

If the car were being moved sideways, could you determine the force on the car by using the weight equation

VashaNatasha [74]

No, if the car were moving sideways, then the forces used would be on the horizontal axis. So the weight equation would be extraneous, unless one is determining the net force through an inclined plane

the maximum normal force a pilot can withstand is about eight times his weight. What is the maximum radius of curvature that a j

neonofarm [45]

Complete Question

the maximum force a pilot can stand is about seven times his weight. what is the minimum radius of curvature that a jet plane's pilot, pulling out of a vertical dive, can tolerate at a speed of 250m/s?

Answer:

The value is $r = \frac{250^2 }{6 * 9.8 }$

Explanation:

From the question we are told that

The weight of the pilot is $W = mg$

The maximum force a pilot can withstand is $F_{max} = 7 W = 7 (mg)$

The speed is $v = 250 \ m/s$

Generally the centripetal force acting on the pilot is equal to the net force acting on the pilot i.e

$F_c = F_{max} - mg$

Here N is the normal force acting on the pilot

Now

$F_c = \frac{m v^2 }{r}$

So

$\frac{m v^2 }{r} = 7(mg) - mg$

=> $r = \frac{v^2 }{6g}$

=> $r = \frac{250^2 }{6 * 9.8 }$

=> $r = 1063 \ m$
