If an object has a mass of 50 kg and is accelerating at 2m/s/s, what is the force it will exert?

1 answer:

5 0

The formula you're looking for is Force = mass * acceleration. this means the force = 50 * 2, which is 100N

Answer:

v = 34.128 km/hr

Explanation:

Given that,

The initial speed of a truck, u = 0

Acceleration of the truck, a = 0.3 m/s²

Distance moved, d = 150 m

Let the final speed of the truck is v. Using third equation of motion i.e.

$v^2-u^2=2ad\\\\v=\sqrt{u^2+2ad}$

Put all the values,

$v=\sqrt{0^2+2\times 0.3\times 150}\\\\v=9.48\ m/s$

v = 34.128 km/h

So, the final speed of the truck is equal to 34.128 km/h.
