Explanation:
It makes it easier to dig a hole because it helps pick up dirt
Answer:
3000 N
Explanation:
We have,
• Mass, m = 1000 kg
• Acceleration, a = 3 m/s²
We have to find force required, F.
F = ma
F = 1000 × 3 N
F = 3000 N (Answer)
Answer:
A 1.5 metres per second squared B 0 C 6 0.5
b) 9m
Explanation:
a= v-a/t
a= acceleration measured in metres per second squared
v= final speed measured in metres per second
u= initial speed measured in metres per second
t= time measured in second
A
a=v-a/t
a= 3-0/2
a= 1.5 metres per second squared
Distance in a velocity time graph = area under
To calculate the distance in the first 4 seconds
You divide the graph into triangles and rectangles
Area A (triangle )= 1/2 × base × height
=1÷2 ×2×3
= 3m
Area B (rectangle)= L×B
=2×3
=6m
Area A + Area B= 3+6
= 9m
