Lisa can run the 100 m dash in 22 seconds. what is her speed?

Speed = distance/ time taken

v = d/ t

v   100m / 22s

lisa speed =    v  = 4.55m⁻²

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

force tends to be low and long diustance masses are high
