Answer:
Magnifying glass and a Petri dish.
Explanation:
Answer:
X=92.49 m
Explanation:
Given that
u= 21 m/s
h= 97 m
Time taken to cover vertical distance h
h= 1/2 g t²
By putting the values
97 = 1/2 x 10 x t² ( g = 10 m/s²)
t= 4.4 s
The horizontal distance
X= u .t
X= 21 x 4.4
X=92.49 m
Answer:

Explanation:
From the question, acceleration from
in 10 seconds.
Acceleration function can be written as:-

From the acceleration equation, we can obtain the velocity equation:

We calculate velocity after 10sec from the above v(t) as
.
To obtain distance travelled after 10 seconds:-

Therefore 200m is for 10seconds, and next 200m at 30m/s
Total time=
