The featured character is the character who dives into water and brings up a small amount of mud or sand.
Answer:
The ratio of forces is 22 : 3.
Explanation:
Case I:
initial velocity, u = 35 mph
final velocity, v = 0
time, t = 15 ms
Case II:
initial velocity, u = 35 mph
final velocity, v = 0
time, t' = 110 ms
let the mass is m.
According to the Newton's second law, the force is given by the rate of change of momentum.
So
Answer:
Yes
Explanation:
sun rays towards the earth is an example of velocity
Answer: Negative acceleration occurs when an object slows down in the positive direction.
Positive acceleration occurs when an object speeds up in the positive direction.
Explanation: Acceleration can be positive or negative. A negative acceleration is also known as deceleration. And deceleration occurs when an object is coming to rest. While acceleration simply means that an object is Speeding up.
Negative acceleration occurs when an object slows down in the positive direction.
Positive acceleration occurs when an object speeds up in the positive direction.
