Answer:
81 m
Explanation:
Given:
v₀ = 0 m/s
a = 2 m/s²
t = 9 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (0 m/s) (9 s) + ½ (2 m/s²) (9 s)²
Δx = 81 m
Even though the object is weightless, it would need inertia, I.e, you pushing it or any form of transportation. So you would still have to push that 500kg to just keep it moving in space. Say if it were a planet with less gravitational force, it would be weightless.
Answer: The time of contact will be 0.006 seconds.
Explanation:
An impulse of a force is the product of average force and the time interval when the force acts.
Mathematically,
Where,
J = impulse = 3.6 Ns
F = Force = 600N
= Time = ?s
Putting the values in above equation, we get:
t = 0.006 seconds
Hence, the time of contact will be 0.006 seconds.
