1 answer:
Answer:
Deceleration of 0.075m/s²
Explanation:
Given parameters:
Initial velocity = 5m/s
Time = 40s
Final velocity = 2m/s
Unknown:
The jogger's acceleration = ?
Solution:
To solve this problem, we use;
a =
a is the acceleration
v is the final velocity
u is the initial velocity
t is the time taken
a =
= - 0.075m/s²

Answer:
250000kg
Explanation:
Mass =density * volume
Density=1000kg/m³
Volume=l*w*h
12.5*10.0*2.0=250m³
Mass=1000 *250
=250000kg
5-14 m/s in 3 seconds
a=vf-vi/t
a=14-5/3
a=9/3
a=3 m/s^2
