PLEASE HELP ASAP 3. JRod is trying to get a cart to reach the wall at the end of the system pictured below. She uses a ramp to get the cart some energy to cover that distance. However, as shown below, using the ramp as constructed, she was not able to reach the wall. a. What can Jrod change to get the cart to reach the wall? b. Explain how you know.​

what type of charge does it have? negative

b would be the answer

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
