Option A is discarded due to the fact that we deserve to not conclude from the statement that is a bird flying 10m/s for 10 seconds.

You are watching: Which object has a varying speed

Option B is correct due to the fact that it is mentioned that a car is slowing from 60 m/s for 10 seconds.

Since, the rate is slowing means speed is changing.

Therefore, alternative B is correct.

Option C and also D room discarded due to the fact that is we have the right to not conclude anything indigenous the offered statement.

From a static warm air balloon, a 10kg projectile is introduced at a rate of 10m / s upwards. If the balloon has actually a fixed of 90kg. W

c. 1.11 m/s down

Explanation:

Momentum is conserved.

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

Assuming the balloon and also projectile are initially at rest:

(90 kg) (0 m/s) + (10 kg) (0 m/s) = (90 kg) v + (10 kg) (10 m/s)

0 kg m/s = (90 kg) v + 100 kg m/s

v = -1.11 m/s

An unmarked police car traveling a constant 95.0 km/h is happen by a speeder traveling 110 km/h . Specifically 2.00 s after the spe

charline-picon.com:

So police auto will overtake the speeder after ~ 5.64 s

Explanation:

Initially the distance between police car and the speeder when police automobile is around to accelerate

now us have

now velocity that police with respect come speeder is provided as

relative acceleration that police auto with respect come speeder

now the time taken to cover the distance between police car and also speeder is given as

c since that is the only time the it is declared that the is applying a force to the watercraft himself instead of just moving the .
