Answer:
Explanation:
The acceleration of the bycicle is given by:
where
v = 20 m/s is the final velocity of the bike
u = 40 m/s is the initial velocity
t = 5 s is the time interval
Substituting numbers, we find
and the acceleration is negative, which means that the bycicle is slowing down.
Therefore, if the block moves from its position of maximum spring stretch to maximum spring compression in 0.25 s, the time required for a full cycle is twice as much; T = 0.5 s.
Answer:
The car appears to be moving 30 km/hr in the opposite direction of the bus.
Explanation:
Answer:
The formula for calculating force is F= Mass × Acceleration
Explanation:
Newton is what force is measured in
