How far will you have traveled on a bus driving 31 m/s for 3 hours.

ryzh [129]

Well, isn’t v=d/t, then by making subject d, d=vt, turn 3 hours into seconds, 1hr=3600sec, hence 3hr=x, cross multiply and you would have converted it into seconds, then put it into your equation of d=vt

A motorist runs out of gas on a level road 230m from a gas station. The driver pushes the 1140kg car to the gas station. If a 14

malfutka [58]

Answer:

The work done is $32.2kJ$

Explanation:

Work is defined as the product of force and distance moved in the direction of application of force.

$W= F*S$

Given Data

distance S= 230m

force F= 140 N

Mass of car m= 1140 kg

Applying the formula for work done we have

$W= 140*230\\W= 32200 J\\W= 32.2kJ$

The work done by pushing the car for a distance of $230m$ is $32.2kJ$

A wrench 0.500 m long is applied to a nut with a force of 80.0 N. Because of the cramped space, the force must be exerted upward

riadik2000 [5.3K]

Answer:

Torque, $\tau=34.6\ N.m$

Explanation:

It is given that,

Length of the wrench, l = 0.5 m

Force acting on the wrench, F = 80 N

The force is acting upward at an angle of 60.0° with respect to a line from the bolt through the end of the wrench. We need to find the torque is applied to the nut. We know that torque acting on an object is equal to the cross product of force and distance. It is given by :

$\tau=Fr\ sin\theta$

$\tau=80\times 0.5\ sin(60)$

$\tau=34.6\ N.m$

So, the torque is applied to the nut is 34.6 N.m. Hence, this is the required solution.
