Answer: Well we see that v= u- ft/m

lets say that ft= feet and m= mass

so you divide those and subtract u

leaving you with the value of v which is 13

Emily uses a rifle to shoot a bullet at a target. The bullet has a mass of 13 grams. The rifle has a mass of 3,500 grams. When s

sp2606 [1]

Force exerted by the bullet = mass * acceleration = 0.013 * 850 = 11.05 Newtons.

the rifle exerts same force in opposite direction so we have

11.05 = 3.5 * a
acceleration = 11.05 / 3.5 = 3.16 m /s^-2

A radio-controlled car increases its kinetic energy from 3 J to 10 J over a distance of 1 m. What was the average net force on t

goldfiish [28.3K]

Answer:

Net force, F = 7 N

Explanation:

It is given that,

Initial kinetic energy of the car, $K_i=3\ J$

Final kinetic energy of the car, $K_f=10\ J$

Distance, d = 1 m

We need to find the average net force on the car during this interval. It is given by using the work energy theorem as :

$W=\Delta K$

$W=K_f-K_i$

Also, W = F.d d = distance and F = net force

$F.d=K_f-K_i$

$F=\dfrac{K_f-K_i}{d}$

$F=\dfrac{10\ J-3\ J}{1\ m}$

F = 7 Newton

So, the average net force on the car during this interval is 7 newton. Hence, this is the required solution.
