Answer:
D
Explanation:
5 Km=5000m
so Δv=5000 m/sec
a=Δv/Δt
=5000/10
a=500 m/sec² as 500÷1000=0.5 Km
a=0.5 km/sec²
so D is the right answer.
Answer:
15Ns
Explanation:
Given parameters:
Mass of the object = 10kg
Force impact = 5N
Time of action = 3s
Unknown:
Impulse applied on the object = ?
Solution:
Impulse is the force that acts on object within a period of time.
Mathematically;
Impulse = Force x time
Now insert the parameters and solve;
Impulse = 5 x 3 = 15Ns
Slope formula : y2 - y1 / x2 - x1
The coordinates are ( 66 , 39) and ( 12 , 83)
83 - 39 / 12 - 66
44 / - 54
slope = - 0 . 81 or - 22/27
