Imagine a car moving at a speed of 10 m/s it starts speeding up at an acceleration of 2 m/s/s. What will the car's speed be afte

alexandr402 [8]

Answer:

14 m/s

18 m/s

22 m/s

Explanation:

The car is moving at constant acceleration, so we can find its velocity at time t using the equation:

$v=u+at$

where

u = 10 m/s is the initial velocity

$a=2 m/s^2$ is the acceleration

t is the time

Substituting the different times, we find:

At t = 2 s:

$v=10+(2)(2)=14 m/s$

At t = 4 s:

$v=10+2(4)=18 m/s$

At t = 6 s:

$v=10+2(6)=22 m/s$

Andrei [34K]

Answer:

Advantage:

It makes work faster and easier

Disadvantage:

The work to its very best

Explanation:

More people reduces the time spent on one work which makes easier to finish but the work might not be done to its very best because different people are doing the job

A deer is running from a mountain lion when it encounters a fence that is 1.50 m high. Seeing the fence, the deer jumps, leaving

Novosadov [1.4K]

Answer:

Explanation:

Given

Initial Velocity (u)=13 m/s

angle $=29^{\circ}$

distance between fence and deer=2.5 m

We consider deer jump similar to projectile motion

equation of trajectory

$y=xtan\theta -\frac{gx^2}{2u^2(cos\theta )^2}$

$y=2.5tan(29)-\frac{9.8\times 2.5^2}{2\times 13^2\times (cos29)^2}$

$y=1.385-0.2368=1.148 m$

Thus deer will cross the fence with an difference in its jump and fence

1.5-1.148=0.351 m

$h_{max}=\frac{u^2sin^2\theta }{2g}$

$h_{max}=\frac{13^2\times (sin29)^2}{2\times 9.8}$

$h_{max}=2.02 m$

so deer rises during when it is over fence

It takes 6 seconds for a stone to fall to the bottom of a mine shaft. how deep is the shaft

Margaret [11]

You need the kinematic equation for distance as a function of acceleration:

$d = [v(initial) *t] + 0.5a*t^{2}$

where a = gravitational acceleration 9.8m/s^{2}
v(initial) = starting velocity
t = time of fall

if the stone started at rest then v(initial) = 0 making the equation simply $0.5a * t^{2}$

Let me know if you still need further help :)
