During a football game, a receiver has just caught a pass and is standing still. Before he can move, a tackler, running at a velocity of 3.70 m/s, grabs and holds onto him so that they move off together with a velocity of 2.00 m/s. If the mass of the tackler is 123 kg, determine the mass of the receiver. Assume momentum is conserved.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

where's the following? you gotta add it to know what the choices are

explanation:

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
