Physics: Uniform Motion
A motorboat maintained a
constant speed of 15 miles per hour relative to the water in
going 10 miles upstream and then returning. The total time
for the trip was 1.5 hours. Use this information to find the
speed of the current.
Ans: 5 mi/hr.
Any solution for this? Thanks

Need this badly today
What work is done on a level track in bringing the velocity of a train weighing 200metric tons from zero to 45 kph, if the frictional resistance at any velocity is 45N/ton, and if the change in speed is accomplished in length of 1000m? (Ans. 26780.95 KN/m)
C. If the track were a 1% upgrade, what would be the additional work to be done?

physics
a soccer ball with mass 0.420 kg is initially moving with speed 2.00 m/s. a soccer player kicks the ball, exerting a constant force of magnitude 40.0 N in the same direction as the ball's motion. over what distance must the player's foot be in contact with the ball to increase the ball's speed to 6.00 m/s?
