Question

Assertion: A car of 400 kg can be accelerated a velocity of 5m * s ^ - 1 in 5 second from its position.
Reason: It can happen if a force of 400 N is acting on it.​

Answer 1

Answer:

Velocity is vector quantity so direction matters.

v i

=25m/s,v f

=−25m/s.1Δv=(−25)−25=−50m/s

Average acceleration = ΔtΔv = 550 =10ms −2.
