4. A high school athlete runs 400 m in 52.20 sec. What is his speed in mph?<br> 14100<br> 1110

Serggg [28]

Answer:

28,800m/p second

Explanation:

Calculate the distance per second so, 400m/50 s= 8m/p second now knowing the speed/hour and knowing an hour has 3,600 seconds,multiply it by 8 then you will get 28,800m/p second, or 28.8km/h

A sled slides along a horizontal surface on which the coefficient of kinetic friction is 0.25. Its velocity at point A is 8.6 m/

jenyasd209 [6]

Answer:

$\Delta t =1.31\ s$

Explanation:

given,

coefficient of kinetic friction, μ = 0.25

Speed of sled at point A = 8.6 m/s

Speed of sled at point B = 5.4 m/s

time taken to travel from point A to B.

we know,

J = F Δ t

J is the impulse

where F is the frictional force.

t is the time.

we also know that impulse is equal to change in momentum.

$J = m(v_f - v_i)$

frictional force

F = μ N

where as N is the normal force

now,

$F\Delta t = m(v_f -v_i)$

$\mu m g \times \Delta t = m(v_f-v_i)$

$\mu g \times \Delta t = v_f-v_i$

$\Delta t =\dfrac{v_f-v_i}{\mu g}$

$\Delta t =\dfrac{8.6-5.4}{0.25\times 9.8}$

$\Delta t =1.31\ s$

time taken to move from A to B is equal to 1.31 s

URGENT What does Newton's third law say about why momentum is conserved in collisions?

valentinak56 [21]

Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.For such a collision<span>, the forces acting between the two objects are equal in magnitude and opposite in direction</span>
