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

A tennis ball with a speed of 11.3 m/s is moving perpendicular to a wall. after striking the wall, the ball rebounds in the oppo

Arlecino [84]

To calculate the average acceleration of the ball we use the formula,

$a= \frac{v_{f} -v_{i}}{t}$

Here, $v_{f}$ is the final velocity of the ball and $v_{i}$ is the initial velocity of the ball t is the time in contact with the wall.

Given $v_{i} = 11.3 m/s$ towards the wall and $v_{f} = 7.2207 m/s$

away from the wall and $t=0.00803 s$ .

Substituting these values in above formula , we get

$a=\frac{(-7.2207 m/s)-11.3 m/s}{0.00803 s}$

Here $v_{f}$ is negative because ball is moving away from the wall.

$a= - 2306 .4 \ m/s^{2}$

Therefore, average acceleration of the ball is $- 2306 .4 \ m/s^{2}$ (away from the wall).

Receiver maxima problem. When the receiver moves through one cycle, how many maxima of the standing wave pattern does the receiv

shusha [124]

Answer:

Two.

Explanation:

A standing wave or stationary wave are the type of wave in which it oscillates with time but the amplitude does not move.

One complete wave consists of two loops.
It means that when the receiver moves through one cycle, two maxima of standing wave pattern the receiver pass through.
