Answer:
i. 7.5 m
ii. 15000 N
Explanation:
Area under vt graph shows the displacement
so area of triangle ABE= 1/2×15×2
=7.5 m
ii) F=ma
here, m=1000kg
and a=v-u/t
=15-0/1
a=15
F=1000×15=15000N
It really depends on the angle where you look at it from and what type of glass/shape they are in. Mine always appeared pretty close even when it wasn't.

Answer:
0.163 s
Explanation:
Appying,
P = mgh/t................ Equation 1
Where P = power of the motor, m = mass of the suitcase, h = vertical distance, t = time, g = acceleration due to gravity.
make t the subject of the equation,
t = mgh/P................ Equation 2
Given: m = 20 kg, h = 50 cm = 0.5 m, P = 0.6 kW = 600 W
Constant: g = 9.8 m/s²
Substitute these values into equation 2
t = (20×0.5×9.8)/600
t = 0.163 s
Answer:
the questions they could ask would be:
how much will the temperature change?
how much pressure will there be?
how durable does the equipment need to be?
how do we know if we will run into a water pocket or a magma pocket?
