2. A 25 kg child riding a bicycle travels to the east at 5 m/s. If he used 50 N of force push the brake pedal in the opposite direction, find the child's initial velocity if it takes 10 s to slow down,
Looking for?
Formula?
Given?
Solution?
50: 251
V
Ft= m (Vf-Vi)

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

the answer for apex is the lowest

which three statements are true about all alloys?

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
