When a force of 50 newtons acts on an object causing an acceleration of 5 m/s2, the mass of the object must be

F = force acting on the object = 50 Newtons

a = acceleration of the object = 5 meter/second²

m = mass of the object = ?

according to newton's second law , force is given as the product of mass and acceleration , hence the formula for force on the object can be given as

F = ma

inserting the values

50 = m (5)

dividing both side by "5"

50/5 = m (5)/5

m = 50/5

m = 10 kg

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
