if jack was traveling north 120 miles and it took him 3 hours to get there. what is the velocity that jack was traveling? is thi

uysha [10]

Velocity of an object is given as

$velocity = \frac{displacement}{time}$

now we have

$displacement = 120 miles$

time = 3 hours

now from above formula

$v = \frac{120}{3}$

$v = 40 miles/hour$

so its velocity is 40 mph and its a vector quantity whose direction is towards NORTH

The mass of the motorbike and rider is 286 kg. Calculate the acceleration of the motorbike at this moment in time.

Aleks04 [339]

Answer:

$a=4.03\ m/s^2$

Explanation:

Given that,

The mass of the motorbike and rider is 286 kg.

We need to find the acceleration of the motorbike at this moment in time.

Net force acting on the bike is given by :

F = 2000 N - 845 N = 1155 N

Let a be the acceleration of the motorbike. So,

$a=\dfrac{F}{m}\\\\a=\dfrac{1155}{286}\\\\a=4.03\ m/s^2$

So, the acceleration of the motorbike is $4.03\ m/s^2$ .

A race car moving along a circular track has a centripetal acceleration of 15.4 m/s? If the car has

Helen [10]

Answer:

r = 58.44 [m]

Explanation:

To solve this problem we must use the following equation that relates the centripetal acceleration with the tangential velocity and the radius of rotation.

a = v²/r

where:

a = centripetal acceleration = 15.4 [m/s²]

v = tangential speed = 30 [m/s]

r = radius or distance [m]

r = v²/a

r = 30²/15.4

r = 58.44 [m]
