Can anyone please explain to me how to work out instantaneous velocity. I do not understand it and how to apply it. Any help would be greatly appriciated.
thank you.
Can anyone please help me with this question?
An electric toaster designed to operate at 240V RMS has a power rating of 600W.
what is the resistance of the heating element in the toaster?
Can anyone please help me figure this question out;
A senior physics class conducting a research project on projectile motion constructs a device that can launch a cricket ball. The launching device is designed so that the ball can be launched at ground level with an initial velocity of 28m/s...

Bowling ball and table!
Can anyone please help me figure this one out;
A bowling ball of mass 7.5kg traveling at 10m/s rolls off a horizontal table 1.0 m high. Calculate the velocity of the ball as it reaches the floor, ignoring air resistance and having an acceleration due to gravity of 9.8m/s.
Could anyone please explain to me how to work the following question out?
A table-tennis ball of mass 10g is falling towards the ground with a constant speed of 8.2m/s. Calculate the magnitude and direction of the air resistance force acting on the ball.
Golf balls and cliffs!
Hi I'm new to this forum and a novice in physics could anyone please help me with this question?
A golf ball is droped from the top of a sheer cliff 78m high. If gravity is 9.8ms^-2 and there is no air resistance, what speed is it traveling at 10m from its initial...
