A 4.5 kg box is being pulled by a girl using a string that makes an angle of 20° horizontal. Find the force of friction if the force exerted on the string is 15 N and the coefficient of friction is 0.5.

What mass will a pumpkin have a force of 450 newton’s accelerates it to 110 m/s^2? include the correct units.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec
