Answer:

Explanation:

Given

velocity of antelope v=10 m/s

antelope needs to cover a horizontal distance of 20 m

considering horizontal velocity antelope needs to cover 20 m in t sec which is given by

t=\frac{20}{10}=2 s

i.e. in 2 sec antelope needs to jump and return to ground for zero vertical displacement

h=ut+\frac{1}{2}at^2

h=vertical displacement

a=acceleration

t=time

for,  h_{max}, t=1 s

h_{max}=0+\frac{1}{2}g(1)^2

h_{max}=\frac{g}{2}

h_{max}=4.9 m

Describe an example of newton’s 3rd law of motion
professor190 [17]

Answer:

For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.
