What acceleration will you give to a 27.8 kg

Physics
1 answer:
stich3 [128]3 years ago
3 0

Answer:

2.72m/s²

Explanation:

Given parameters;

Mass of box  = 27.8kg

Force on box  = 75.7N

Unknown:

Acceleration  = ?

Solution:

Force is the product of mass and acceleration;

   Force  = mass x acceleration

Now insert the parameters and solve;

    75.7  = 27.8 x a

       a = \frac{75.7}{27.8}  = 2.72m/s²

At what distance along the central perpendicular axis of a uniformly charged plastic disk of radius 0.390 m is the magnitude of
aliina [53]
<span>Radius, the distance from the centre = 0.390
 Electric field is equal to half of the magnitude. E2 = E / 2
 Given
E1 = E2 E1 = k x Q / r^2
  E2 = (k x Q / r2^2) / 2
  Equating the both we get 2 x r^2 = r2^2
 r2 = square root of (2 x r1^2) = square root of (2) x r = 1.414 x 0.390
  r2 = 1.414 x 0.390 = 0.551 m</span>

PLEASE I REALLY NEED HELP!
Talja [164]

Answer:

v=\dfrac{1200}{t}\ m/s

Explanation:

Given that,

The car traveled a total of 1,200 meters during this test.

We need to find the average speed of the car. The average speed of the car is given by total distance covered divided by the time taken. So,

v=\dfrac{1200}{t}\ m/s

But putting the value of t we can find the average speed of the car.

A flare is launched from a boat. The height, , in meters, of the flare above the water is approximately modelled by the function
Tpy6a [65]

Answer:

10 seconds

Explanation:

If the height is modeled by the function h(t)=-15t^{2} +150t, then the seconds it takes to reach the water (when the height equals 0) is modeled by the following.

0=-15t^{2} +150t\\0=-15t*(t-10)\\\\t=0\\t=10
