A sports car accelerates from 0 to 60 mph, 27 m/s, in 6.3 seconds. The car exerts a force of 4106 N. What is the mass of the car?

My answer yield 955kg but I am not sure with my solution. Please help! Thanks.

I need your help masters in physics!!

A boy can accelerate at 1.00 m/s2 over a short distance. If the boy were to take an energy pill and suddenly have an ability to accelerate at 5.6 m/s2, then how would his new energy pill force compare to his earlier force? If the boy's earlier force was 45 N, what is the size of his energy pill force?

This might be very easy but Im going nuts here! Help is greatly,deeply appreciated.

Thanks y'all!

A freight train traveling with a velocity of 18.0 m/s to the south begins braking as it approaches the train yard. The train's acceleration while braking is -0.33 m/s2. What is the train's speed after 23 seconds?

I suck at physics! Your help would be grateful.

A body with an initial velocity of 8 m/s moves with a constant acceleration and travels 640 m in 40 seconds. Find its acceleration.

The answer is a= 0.4 m/s2 but i can't seem to get the right answer or the formula.

Thank you!

sorry but i don't get these word.its jargon for me.can anyone explain?

just asking.

why do we need to disable it when we are having issues connecting online?especially for a windows vista computer.pls help!
