What is the mass of a crate if a force of 200 n causes it to accelerate at 8 m/s2? (formula: f=ma)

m = 25 kg

Explanation:

F = ma

mass = 25 kg

Explanation:

Force is said to be the push or pull upon an objects with mass resulting to the change in velocity of that object. Force is a vector quantity. Force has both magnitude and direction. The direction where the force is applied is the direction of the force. Force can be measured using spring balance and the S.I unit of force is Newton.

Force is said to be the product of the mass of a body and the acceleration.It can be represented mathematically as

F = ma

Force = mass × acceleration

F= 200 Newton

a = 8 m/s²

F = ma

since we are ask to find mass , we make mass the subject of the formula

m = F/a

m = 200/8

m = 25 kg

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
