A box with a mass of 100.0 kg slides down a ramp with a 50 degree angle. What is the weight of the box?
981 N
What is the value of the normal force? Round the answer to the nearest whole number.

What is the acceleration of the box? (Disregard friction and air resistance.) Round the answer to the nearest tenth.

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
