Answer:

72 km/h

Explanation:

Speed of car = 20m/s

So, here to find the speed in km/h we will change the metre to km and seconds to hours .

$\frac{20}{1000} \div \frac{1}{3600}$

= 72 km/hr

to change into km divide by 1000

(1 m = 1/1000km)

and,

to change into hours divide by 60*60= 3600

A 20 N unbalanced force causes an object to accelerate at 1.5 m/s2. What is the mass of the object?

Ket [755]

Answer:

Force = 20N

acceleration (a) = 1.5 m/s²

Mass of object (m) = ?

From Newtons II law

F = m. a N

m = F/a

m = 20/1.5

m = 13.34 Kg

Mass of an object is 13.34 Kg
