A gold ball has a mass of 45g. In a speed test, a golf ball was driven from rest to a velocity of 90m/s. a) If the time taken for the golf ball to reach this velocity was 0.0005 seconds. What acceleration was this?

b) What forces was applied to the golf ball?

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
