Answer: 1.96 m/s
Explanation:
Given
Mass of Professor
Velocity of professor
mass of chair
velocity of chair
Suppose after the collision, v is the common velocity
Conserving momentum
Answer
The direction of the sun’s pull relative to the planet’s motion changes.
Explanation:
Explanation:
Average velocity = displacement / time
v = (25 m − 2 m) / 4.5 s
v = 5.11 m/s
because positive and negative attract
Answer:
4680 N
Explanation:
Force =mass x acceleration
Mass =1800kg
Acceleration =2.6m/s ^2
Hence Force = 1800kg x 2.6m/s
= 4680N
