Answer:
4680 N
Explanation:
Force =mass x acceleration
Mass =1800kg
Acceleration =2.6m/s ^2
Hence Force = 1800kg x 2.6m/s
= 4680N
The cheetah's speed is 100x and
The gazelle's speed is 80x + 70.
Set the two equations equal to each other:
100x = 80x +70 (then subtract 80x from both sides).
20x = 70 (then divide by 20).
X =3.5.
The cheetah catches the gazelle after 3.5
Double
Explanation:
Since the period T of a pendulum is given by

By increasing the length of the pendulum by 4, the period becomes

You can see that the period doubles when we increase the length by a factor of 4.
