Sebuah mobil ditarik pada kecepatan konstan pada jalan miring menggunaksn tali baja pada C. Mobil mempunyai massa 1800kg dan pusat massanya pada G ( percepatan gravitasi 9,81 m/s² ) Roda bebas menggelinding sehingga rolling resistance diabaikan. Tentukan besar gaya T pada tali baja penarik pada C dan gaya reaksi pada roda depan dan belakang!

Aball is thrown horizontally from a cliff at 8m/s .in what direction is the ball moving 2s later?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
