Answer:
See the answers and the explanation below.
Explanation:
To solve these questions we must understand that speed is the relationship between the displacement and the time that the displacement lasts.
1. 300 [km], in 5 [hr]
d = displacement [km]
where:
v = velocity [km/h]
t = time [hr]
In one hour :
b. Car B 100 [km] in 2 [hr]
C. The car A has the greatest average speed.
Answer:
The change in momentum experienced by the bowling ball is 96 kgm/s.
Explanation:
Given;
mass of the bowling ball, m = 12 kg
velocity of the bowling ball, v = 8 m/s
time of motion, t = 10 s
The change in momentum experienced by the bowling ball is equal to the impulse experienced by the bowling ball.
ΔP = J = F x t
Therefore, the change in momentum experienced by the bowling ball is 96 kgm/s.
