Question

A cheetah can accelerate from rest at the rate of 4m/s2?
a-what will be the velocity attained by it in 10s?
b-how far ot will travel in its duration?

Answer 1

Answer:

a. 40m/s^2

b.200m

Explanation:

acceleration (a)is 4m/s^2

initial velocity(u) is 0

time(t) is 10 sec

final velocity (v)is not given

using the first equation of motion

v is equals to u plus at

• v is equals to zero plus 4 multiply 10
• v is equals to zero plus 40
• v is equals to 40m/s

s is equals to ut plus 1/2 at^2

• s is equals to zero multiply 10 plus 1/2 multiply 4 multiply 100(10^2)
• s is equals to zero plus 200
• s is equals to 200
