A vehicle travels from a 30m marker to a 100m marker. What is the change in distance

alexgriva [62]

70 meters is your answer

Note that the beginning is the 30 meter mark, and the ending is the 100 meter mark. Subtract the beginning amount from the end:

100 - 30 = 70

The vehicle traveled 70 meters.

A boy pushes a 50 kg wheelbarrow with a velocity of 0.5 m/s. If he uses a force of 10 N, how far does he push

labwork [276]

Answer:

d=1.25 m

Explanation:

fd=.5mv2-.5mv1; 10(d)=.5(50)(.5)-0; 10(d)=12.5; d=12.5/10; d=1.25 m

What impulse must be applied to a 25.0-kg cart to cause a velocity change of 12.0 m/s?

klio [65]

Answer:

Impulse of force = 300Ns

Explanation:

Given the following data;

Mass = 25kg

Change in velocity = 12m/s

To find the impulse;

Impulse is given by the formula;

$Impulse \; of \; force = mass * change \; in \; velocity$

Substituting into the equation, we have;

$Impulse \; of \; force = 25 * 12$

Impulse of force = 300Ns

The following position vs time graph shows the motion of an object along its path from -10 to seconds. Based on this graph, what

Marrrta [24]

∆x (displacement) = v - u

where, v is the final position and u is the initial position.

Given, the final position of the object is 0 m and the initial position is 5 m.

∆x (displacement) = v - u

= 0 m - 5 m

= -5 m

Therefore, C: -5m is the correct answer.
